Remember when Google launched Gmail back in 2004? It was invite only, and initially through bloggers on its Blogger.com platform. It was the first web anti-launch that I remember being so successful that I took part in (as a pawn, rather than doing its PR or whatnot).
Today there are lots of rumours of Gmail launching a new interface. I hope we see some kind of interesting PR launch to go with it. Gmail has a huge fan base. For something as (hypothetically) dull as an email programme, that's kind of interesting I think. They've done well to achieve that. But personally I'd like to see what's new soon as I'll be using it on my iPod Touch when it arrives next week and need to plug Gmail into it so that I can do a nerve centre hotwiring of the thing :-)
