I would like to complain about a very minor point though, but one that drives me bonkers. The overuse of the word "manifesto" must stop. I even wrote an article attempting to collect all the internet manifestos. It went on for a long time, and didn't come close. http://tiny-giant-books.com/blog/after-the-agile-manifesto-s... Now there is a new entry.
A manifesto is a political document calling for change. This is much more of a to-do list. Or a how-to article. Or a event helper. Anything but a manifesto! :)
While we're on content nits, you might want to add anchors to the headings for deep-linking. Also an alternate chronological view would be even more useful. Like I said, we plan on using this. If we work it into more of a calendar view, I'll post in this thread.
On a less snarky note (sorry about that), it seems like a good check list for putting together an event I'd like to attend. As someone else noted, none of the demo-parties and hackathons I've attended have ever checked off every box. On the other hand, it might be a cultural thing -- I imagine these events to be more developed around the valley where they're more common.
But if you ask me, it has a wonderful feel to it already. The thing about the word "manifesto" is that it doesn't match the tone. A manifesto is something that points out the flaws and announces it is time for change. The unabomber wrote a manifesto. Marx wrote a manifesto. The Agile guys wrote a manifesto. Manifestos are rants with calls to action. This didn't have enough rant to it.
Like I said, a very tiny nit. If it weren't for my hang-up with the word, I wouldn't have mentioned it. An altogether terrific job.
In general http://lanyrd.com/ is the closest I've found, but it's still not comprehensive.
