I’ve long held that social media is a force for good and here’s a nice little illustration of this. Tonight sees the Harvest Twestival in a venue off Trafalgar Square.

But this goes beyond Twitter users simply getting to know each other – there’s a real conscience behind it.

All profits from the evening go towards The Connection at St Martin’s In The Field, which does sterling work with London’s homeless. Attendees have also been encouraged to bring along cans of food that will be donated to the soup kitchen.
