The open source based microblogging platform identi.ca has recently added some cool new features:
- hip new design giving the platform a fresher look;
- cloud tags for individual micro-bloggers;
- and the best of all, groups! You can create groups, join existing ones and write posts inside groups writing “!” in front of the group name.
Adding groups functionality is a nice feature, inspired (maybe?) in FriendFeed’s rooms. People with similar interests can discuss topics together and you’ll always receive posts of the groups you’re connected to.
Since identi.ca’s platform is completely open source, you can download the laconi.ca and create your own microblogging instance with all of these features.
