Whatever else Twitter might be, we've found it a good way of to keep tabs on politicos and reporters, what they're doing, saying and so forth. Pols make unguarded or revealing statements, sometimes just helpful heads-ups on events or statements; reporters give early tips on stories. And just atmospherically you can get a feel for what certain groups of people are thinking and talking about. It's not perfect. Obviously, people know they're being listened to. But it's still a very useful tool.

So with that in mind we set up a series of Twitter rooms that pull together the Twitter feeds of different groups. Here's the feeds for Elected Dems on Capitol Hill, Elected Republicans on Capitol Hill, Democratic and liberal insiders, Republican and conservative insiders and reporters and bloggers.

Each page is auto-updating every few minutes.

The elected officials on Capitol Hill rooms should include every representative and senator on the Hill who has a Twitter account. The others obviously required some subjective judgment as to who to include. But they're fairly comprehensive. And obviously if there are people who you think we should add to one of the lists, please let us know.

They're permanently linked on our front page, below the fold on the right, just across from our masthead.
