Well I am. And it's looking like it's going to be a lot of fun.
Admittedly, I'm a bit of a social butterfly at times and would go to the opening of an envelope if there were enough interesting people there. But this one really does look like an interesting concept.
If you haven't heard of it, then it's probably because you're not on Twitter. (And you're no-one if you're not on Twitter, according to The Twitter Song.) Because the concept of the the Harvest Twestival is to bring together 200 or so twitterati so we can see the real person behind the avatar and the 140 character musings at Doon on Trafalgar Square. (If you're interested in mobile twitterers, then Emily Freeman recently outed a few of us on her blog as 'ones to follow' - thanks Emily!)
The music on the night will be provided by the Madhouse Collective who will be integrating requests from internet channels that have been set up. Kai Fish from the Mystery Jets will also be DJing an exclusive set on the night. (I'm liking the sound of this I have to say.)
All profits from the night will be donated to The Connection at St Martin-in-the-Fields, a community centre based in Trafalgar Square that works with homeless people. Raffle prizes have been donated by the lovely people at Twitter, Firebox.com, Thomson Reuters, ITV and Harper Collins. And the event is made possible by the generosity of its sponsors - UnLtd World, Huddle, Diffusion PR, Tactile CRM, Winston & Strawn LLP and Just Giving.
All in all, it's shaping up to be a good night. And I'm guessing that there'll be a lot of twittering about it later.
