Swear on Twitter. Raise money for #famineaid

What a brilliant idea and a great use of Twitter. You simply pledge to pay £1 per motherloving swear, and connect your Twitter account. SwearJar monitors your swearing, and tweets you a link to pay up after a week.

You swear like a shucking trooper, use the hashtag #fuckfamine, and raise lots of money for the UNICEF famine appeal. Brilliant.
