I just got invited by email to “the second London official flash mob”. Telling me that, depending on my star sign, I should turn up to a particular bar at 6.10pm on Thursday, mill about for a bit, and then go home.

I'm bored to tears reading about flash mobs. And they annoy me. Especially when they involve doing something vaguely wacky.

But they could be abused in a useful way, if people really are so pliable about their activities. For instance, the third flash mob could be: turn up at Kings Cross Water Rats on Thursday at 8.15pm and pay five quid to watch a load of livejournallers sing to you. But somehow I don't think they will.

I feel like ranting extensively about flash mobbing but I must now go to the bathroom.
