Foamee.com is a fun IOU system built on Twitter that helps you track who you owe beers to (and vice versa). All you have to do is follow the account "ioubeer" and then send it @replies. So, say you owe me a beer for helping you change a flat tire, this is what you'd send to Twitter: @ioubeer

Last.fm on their recent aqcuisition by CBS

I just came back from a trip to San Francisco. Apart from having a great time, I discovered a new social media site that just blew my mind and blows the competition away.... Yelp.com is not a new idea by any stretch of the imagination -- haven't reviews of local restaurants, nightlife, bars, businesses, etc. been done to death? Citysearch, for instance, founded in 1995 by idealab, would have cornered the market in local reviews, right?

iStalkr is a web app that allows you to create a lifestream (based on Jeremy Keith's Lifestream concept) tracking all your RSS and ATOM feeds for services you use, like Digg, Del.icio.us, Ma.gnolia, Flickr, Last.fm, Google Reader's Shared Items, Tumblr, Twitter , etc, and create a time line of your activities. You can paste this time line data into on your blog or use the data in other apps. iStalkr then utilizes that data socially, like twitter, where you can monitor your friends time lines and other people can monitor yours.

The Fidg't Visualizer allows you to play around with your network. You interface with the Visualizer through Flickr and LastFM tags, using any tag to create a Magnet. Once a Tag Magnet is created, members of the network will gravitate towards it if they have photos or music with that same Tag.

ConceptShare allows you to easily share designs inside Workspaces that contain designs related to a certain topic or project. It’s easy to invite people into a workspace. Invite team members, managers, clients, and consultants to add and reply to comments, chat and markup designs. People do not have to be in the workspace at the same time to contribute. Workspace members can log-in anytime to any workspace they are member. If members do happen to be in the workspace at the same time they can collaborate with real-time chat and real-time comment updates and concept updates. Paid accounts can manage multiple workspaces and premium accounts can be branded to your logo and colors.
