Do you have time to search the web everyday to find the newest and coolest social media tools? If the answer is no, then you have come to the right place. (& if the answer is yes, leave a comment with your favorites). I have searched the World Wide Web for social media information all week, and stumbled upon a few favorites along the way.

Here are my picks of the week:

Location, Location, Location

Facebook & Location:

This Tuesday, it was announced that Facebook will soon be adding location-based features to their site. Starting next month, the 400+ million Facebook users will be able to start seeing the current locations of their friends. Facebook will be announcing more details at the f8 conference at the end of April.

Twitter & Location:

Twitter is also putting more weight on geolocation. This Tuesday, Twitter turned on geolocation on their website for the first time. Twitter’s geolocation feature has been live through its API since last November, but this is the first it’s being integrated into the main Twitter website.

Foursquare & Location:

Foursquare is also upping their location-based app this week. They’ve revamped their iPhone app, announced new analytics tools for businesses, and has had their biggest check-in day ever. As foursquare tweeted on Thursday, “today is officially @Foursquare’s biggest day ever, Broke 275k checkins hours ago. Wow.”

Google App Marketplace:

This week, Google launched a new app store called Google App Marketplace. This new online store allows you to find, purchase, and use web-based applications easily through Google, and it allows developers to sell software directly to Google’s customers.

SXSW:

Today marks the kickoff of South By Southwest, a conference/festival in Texas that mixes interactive, music, and film. The interactive portion starts today and goes through March 16^th. For those of you heading to SXSW, Mashable has The Complete Social Media Guide for SXSW 2010. For those of you not heading to Texas, you may want to check out your favorite social media sites this weekend to get the latest news and updates.
