Mike Potter (from Adobe) has issued an invitation for all PHP and Ruby developers attending the MAX Conference to track each other down, as well as him.
I think this would be a perfect time for these groups of people to get together, showcase what you're working on, and talk about the problems that you're facing. We're working out the details of MAXUP, but if you're going to MAX, plan on arriving on the Sunday so that on Monday we can get together and showcase and talk about the work that's going on with Flex and languages other than Java and ColdFusion.
He suggests using the entry's comments to help coordinate the meetings. The Early Bird pricing is still in effect for the conference, so there's no time like the present to reserve your spot.
