I didn't attend, though evidently there was some drama LJ-style in the comments to the announcement.
This past weekend I almost decided not to attend the Metro Makeout party taking place on Vancouver's SkyTrain, my excuse being that because of the media attention, it would be attended by enough people to 'document' it. Though I didn't participate, I'm glad I went, and even took some photos of the event. (If you're squeamish about girls and dudes making out with each other, then there are better links to click on than that one.) For some background and photos, see the writeup of the 8 Hour Makeout as well as the follow-up of Metro Makeout by the event's organizer. Like I said, I didn't participate, the excuse being that all the people kissing were gay, which is of course bullshit because not all of them strictly identified themselves as such, so it was mostly squeamishness of kissing someone I never met. It got a little steamy at one point, especially on the way back, and the reactions of the onlookers was worth the price of admission (note: there was no price of admission, and no political statement other than that kissing is fun).
It looks like Roland is trying to give Vancouver the label "Makeout City", and though Jay has a lock on both the domain and the phrase, the sentiment is right. Team Makeout wants to give this city a kick in the pants, and their events, pseudo-secret up until close to when the event occurs, are steps in the right direction.
