Ooooh, it's going to be an exciting London Java Meetup tonight!

Firstly, we've got Hani versus James and the Groovy boys arguing about Groovy. Despite what Sam says, I'm not against Groovy as such, but I have my own favorite, and with religious wars, you often get a with-us-or-against-us kind of thing going on. ;-)

Then, for the 2nd act, you'll have the Thoughtworkers having a full and frank exchange of views with Hani, who's been dissing them and their Guru.

Should be fun.
