Selective Twitter plugin?

Hey there!
I was wondering if there was any option how I could post selective tweets to, say, my sidebar? I’d be grateful if you could point me in the direction of a plugin (or a widget) that is able to do this, if possible for multiple twitter accounts as I’m sharing a blog with friends.

Or does anyone know another solution for those “micro-updates” that don’t really qualify for an own post but I’d still like to be visible somewhere on my blog?

Any help appreciated! Thank you in advance! ??
