It's 5:31am and I can't sleep - so what better thing to do than create a spider to read all the Greenlight Games into a local database and have a meander through the stats!! :)
Steam is dead slow at handing-over the pages (probably deliberate) so it's taking a while (at least another 10 mins before I'll have a near-complete list) but there are some interesting things popping-up already - like the fact some games have an upload date WAY before the service went live (uploaded by Valve for testing perhaps?)
I'll post more juicy information - perhaps even a link to the raw data - if you're curious at all. Hell if you speak PHP (and a bit of jQuery for the output) I'll throw you the source and YOU can get IP banned by Steam too :)
p.s. I'm finally tired and it's only 'found' 500-odd of the 600-odd games - but here's something to go on until I wake-up and get coffee again :)
