You've probably noticed Twitter's (news, site) new Activity tab by now. The section displays interesting information about the people you follow, such as which tweets they've recently starred and who they've added to their network:
Obviously the move resembles Facebook's own News Feed, which also displays recent activity from the people in your network. Some of you may have seen this coming, as most network-y, community applications in both consumer land and the enterprise are following this template. Let's name a few just for fun: Google+, Salesforce's Chatter, Yammer, Socialcast, MangoApps -- the list goes on.
In Twitter's case, the key difference lies in the approach. While Facebook's News Feed is front and center,Twitter's activity stream must be selected from the row of tabs if you want to view it. Keeping this information away from the forefront keeps Twitter's homepage from looking too cluttered while simultaneously giving users more reason to extend their visit time.
Another new tab, @[your user name] wades through activity even further by giving you an aggregated view of all of your personal activity, such as who has followed you, starred your tweets or sent you a @mention.
Twitter's official blog post on these additions says the changes are aimed at helping users discover more information, and while that's certainly true, I can't help but also see it as yet another example of how consumer and enterprise applications are converging under one umbrella of functionality -- and Facebook is leading the pack.
