Mit TwitterSnooze kann man Mit-Twitterer sozusagen auf Zeit *muten*:

Warum:

• It's a good tool to avoid a blast of tweets from a conference you are not attending... just snooze the conference goers for a few days.
• It's a nice way to get back at someone for saying something stupid... give them the silent treatment ;)
• It's a good way to ignore someone that just flooded your timeline for no good reason... but it was just a one-time offense and doesn't merit permanent unfollowing.

Minus:
der Gesnoozte bekommt eine Nachricht über seinen Status zugesendet - aber: wer will schon subtil sein...

Bitte snoozt mich nicht :-)
