With SXSW starting Friday in Austin, Texas, every location-based service out there is right now finalizing updates that they hope will be the one that gets them used more than all the others. Loopt, is betting on events integration.

The latest version of the app, due to hit the App Store tomorrow will feature a new Pulse tab. Here you’ll find events populated from a ton of sources including the live music tracker SonicLiving (SXSW is first and foremost a music event, after all) and most notably, Facebook. This pre-population is important, because it means the events will already be in the system so users won’t have to do anything other than share it with friends, or check-in if they’re going. The feature also uses you current location to show which events are happening around you at any given moment that a lot of people are at.

Business to business software can be a tough sell. Online B2B is can be even a harder sell. While there is certainly money to be made, unless you’re one of the big players, the likelihood you’re going to succeed is pretty small. Starting today, Google is taking their roll as one of the big players and extending a platform to boost some smaller players.

Tonight, Google has unveiled their Google Apps Marketplace. What this is is essentially an app store for enterprise apps in the cloud. Using a set of APIs, these third-party apps can deeply integrate their product within Google Apps, which already some 25 million people are using. And that also includes over 2 million businesses ranging from startups, to small businesses, to Fortune 500 companies.

For customers, this means a one-stop shop for a variety of applications that their business or organization can use. And it’s extremely simple to get started with apps in the marketplace — it just takes 4 clicks, Google says (though that initial click will have to come from your domain admin to approve the use of the app). For developers, particularly small startup developers, it means instant access to more users than they can likely imagine. It also potentially means something more important: money.

SV Angel, the angel fund founded by super-angel Ron Conway, is losing one of its general partners to a portfolio company. Brian Pokorny is now the CEO of fast-growing Silicon Valley-based Dailybooth.

Dailybooth, the runner up in the “best social app” and winner of the “time sink” categories at this year’s Crunchies Awards, is “your life in pictures.” Some 6 million monthly visitors share pictures and status updates with eachother. “It’s a community for self expression,” says Pokorny.

A typical interaction: a users posts a photo, taken with their webcam, showing what they’re eating, what they’re feeling, or perhaps with friends in the background. Other user then respond via text or photos. Some strings go on for hundreds of responses. Here’s an example.

Twitter has quietly changed the wording on the button users need to press to update their statuses on the Twitter.com website. It took them 10 billion (or so) tweets to realize we don’t ‘Update’, we ‘Tweet’.

A lot of people are noticing the change, although I have to say I had to hit the refresh button of my browser a couple of times before I saw it too.

We’ve written about Twitter client Sobees, which is working to create the best social media client on the market, competing with both TweetDeck and Seesmic. Today Sobees is releasing a new version of its Windows native desktop app built in .NET, complete with realtime search, a redesign and more.

The new client includes support for Facebook, Twitter, MySpace, FriendFeed and LinkedIn (which was added late last year). The most significant addition is the availability of realtime search on the client, with the ability to search Twitter, Friendfeed, OneRiot and FacteryLabs from within the application. Sobees integrated elements of its newly launched realtime web dashboard to power search in the client.

It’s a little surprising to see a Twitter application coming out of Fuze Box (formerly CallWave), which creates visual collaboration product. The company has clearly caught the Twitter bug (albeit a little late) and today is launching Tweetshare, an third party Twitter app that allows anyone to immediately publish any type of content to the web, including HD video, presentations, images and more and automatically start Twitter conversation threads around their content. It’s kind of like FriendFeed meets Twitpic or Twitvid. Tweetshare has also rolled out a companion iPhone app that allows mobile users to upload content, tweet and create discussions on the Tweetshare platform.

A social alternative to static landing pages, Tweetshare aims to be a Twitterfied-Facebook Fan Page. Twitter users can post relevant content, such as presentations, images, videos and PDFs, and can also Tweet from the platform. Any comments made on a Tweetshare page or similarly, made on Twitter in response to posted content is also threaded on the page. A free application, Tweetshare also provides measurement and analytics tools, including polling functionality and the ability for users to become a fan of a brand’s Tweetshare Fan Page. And similar to YouTube channels and Facebook pages, Tweetshare Fan Pages can be branded and customized.

Online retail sales aren’t growing at the torrid pace they once were, but they continue to grow steadily. Forrester Research put out a new five-year forecast today predicting that e-commerce sales in the U.S. will keep growing at a 10 percent compound annual growth rate through 2014. It forecasts online retail sales in the U.S. will be nearly $250 billion, up from $155 billion in 2009. Last year, online retail sales were up 11 percent, compared to 2.5 percent for all retail sales.

Some other stats from the U.S. forecast:

Brazil is sort of a strange country to throw into the “emerging market” category. It’s not a particularly young country like India or Israel, nor is it a country like China or Russia that embraced capitalism fairly recently. Brazil is as old as the US and has had a decently built out infrastructure of things like roads and phone lines for some time.

Yes, it’s a growing country with a young and stabilizing democracy that has a long way to go in terms of technology, modernization and bridging a quality of life between very wealthy and very poor. In that sense, it shares enough in common with emerging markets that Wall Street, at least, tosses it in the “BRIC” bucket. Indeed, Wall Street has had a way bigger crush on Brazil to date than Silicon Valley.
That seems to have had two effects on the startup scene in Sao Paulo.

We just came across Packrati.us, a simple bookmarking service that allows you to essentially sync your Twitter feed with your Delicious bookmarks. Once you sign up with you Twitter and Delicious accounts, Packrati will follow your Twitter feed, and whenever one of your tweets contains URLs, the site will add them to your Delicious.com bookmarks.

You can also bookmark URLs in @replies to you. In your Delicious account, the service will include any hashtags you include as tags for your bookmark and include the full text of the tweet in the bookmark comments. Here’s an example of the White House Twitter account’s tweeted URLs in Delicious, using Packrati’s tool.

You know how TweetMeme started out trying to be the Techmeme of Twitter before it ventured off plastering its ReTweet buttons on every blog on the Web? Well now there’s a site that just launched today that wants to be the TweetMeme of Google Buzz called ReBuzzThis.

It is not much to look at right now—five lame links as of this writing. But the site wants to encourage blogs and other sites to add its ReBuzz buttons to posts and articles. The posts that get ReBuzzed the most shoot up the homepage just like on TweetMeme with ReTweets. Except that TweetMeme tries to count all retweets, not just those done through its buttons. ReBuzzThis seems to only count Rebuzzes done through its site and buttons, so it is not really capturing the most Buzzed about articles and posts.
