There are a few reasons i'm not on twitter

I don't really understand how it works, it's impossible to sound like a man whilst saying 'i tweeted that' and i'd be forever writing things like 'Ed is at________ for dinner. Glad he ate first.' It's just too much bother. I am in a bit of a minority though so here's some excellent stuff on Christians using twitter:

Gethin Jones
iMonk
Josh Harris (this reminds me of something that Craig Mackay said to be once: 'we're all lead worshippers.' very, very wise)
John Piper
