For those who didn't hear about it, the 2nd annual MediaWiki Developer Meet-Up (assuming it's meant to happen every year) is happening in the same place as last year, in Berlin on April 14-16:
The focus for this one is "structured (meta) data, search, and community building"; and I'd have to assume the first one of those relates either somewhat or heavily to Semantic MediaWiki. So it would be cool if some SMW-based developers showed up - I don't know if I can yet, by the way. Is anybody else thinking of going?
By the way, the event last year became "sold out" just a few weeks after it was announced - they only had room for about 50 people. I don't know if they'll have room for more people this year, but it's probably worth registering early.
