Snooze Function
So I twitter as do a lot of folks at this stage. However, at times so twitters have extensive bouts of twitterific verbal diahorrea and if you are getting updates via your sms you’ll use up the 250 sms in a matter of hours. So to stop this you can give someone a time out. you can put them on snooze

Great idea - but the ‘wake-up’ notification to the crashing bore would make things just too socially awkward for my liking.
