Temporarily mute people you follow if they suddenly get verbose for some reason (conference tweeting, neverending discussions/rants, etc.).
You can use our lovely bookmarklets, a DM or our full website to mute noisy friends by name or by keyword/hashtag. Head over to the Tools area to check 'em out at http://muuter.com/tools.
We use OAuth, so we don't ask for your password.
I love the idea behind Muuter; without it, you'd have to either bear with annoying "once in a lifetime" tweeting or unfollow people and remember to follow them back. I also use Muuter in "test mode": when I'm beginning to wonder if one particular user should be unfollowed, I muute them first just to see how my timeline looks without him and if I miss him...
Muuter is awesome. I use it in "person" mode, mostly when group-type accounts (e.g. @woot, @whitehouse) go crazy and start spamming every few minutes. I also use it in "keyword" mode, but less often, when too many people I follow are going nuts about something I don't care about.
I do wish there was a way to filter *just* keyword-matching tweets without actually unfollowing, but I recognize the limitations imposed by the Twitter platform and Muuter is certainly the best way of dealing with it for now.
