I’m just about to pack up my laptop and head over to Aperitweat, a cool gathering of Tweeple organised by the inimitable @tojulius.

It’s been publicised via his Twitter friends, registration was via Twtvite, a live Twitterstream will be at the event (hashtags #aptw or #aperitweat), and the whole thing is being streamed live via Ustream.

So in addition to the skills and contacts Julius already has (see the eventmanagerblog for examples), the marketing cost is nothing for a brilliant range of coverage which has packed the place to capacity.

Another example of the ability for self-forming events for little or no cost.

And that’s just a relatively low-profile example in a week when Twitter was used to attempt revoluation in Moldova (see some coverage via Nick Carr and All Things Digital).

And it’s in the week when the first drill has been created with some of the amazing $250,000 raised by the Twestival event in 2020 cities worldwide.
