It used to be that if a link was worth sharing, people would bookmark it for all to see on del.icio.us. Now, they just Twitter it (with a shortened URL). Wouldn’t it be nice to be able to separate out all the Tweets with links in them, and sort them by time or popularity? That is what MicroPlaza does in a nutshell.
MicroPlaza is still in a very limited private beta, but I have 100 invites for TechCrunch readers. Once you log in, you are presented with a stream of headlines, along with everyone who Twittered the link to that page. You can see a personal timelime made up only of links from people you are following on Twitter, or a public timeline to see what everyone is linking to. Each timeline has its own RSS feed.
The headlines can be sorted chronologically or by popularity. The more people who Twitter about the same link, the more popular it gets. Each time someone Tweets a link, it becomes more popular (although there is a time-decay function so that you only see the most recently popular links and associated headlines.
Since most of the time these links are articles or blog posts, MicroPlaza distills the headlines for you and gives you a sense of what is capturing everyone’s attention on Twitter. Any headline can be bookmarked, and you can group the people you follow into different “tribes,” and then keep track of each tribe. MicroPlaza also lets you look at everyone you are following and see their most recent links.
