Ok, this news is like 6 days old, but it's still cool. FriendFeed now has "rooms." That's a different way of saying groups.
You can create your own group or join an existing one. It's a great way to just check out updates from a certain group of people. Thus, the reason the word group was even invented.
For example, there's a new group for peeps from North Carolina, where yours truly resides. This will be a great way to catch up on what's going on nearby, such as networking events - especially when Twitter is down, which has been a lot lately.
(Speaking of Twitter, they need groups too!)
I like FriendFeed's growth. First, they got everyone to sign up. Then they added search, and now they have rooms. Steady and slow, just the way growth thrives. I think they have their best tricks still up their sleeves. I hope so, because I still need something more from them in order to be a regular FriendFeed user, you know, on the level of Twitter.
