UPDATE: DOTA 2 is now freely available to all, so this giveaway is over.
We have 15, count them 15, Dota 2 keys to giveaway, thanks to Valve… by which I mean they just dropped a whole bunch into my Gift Inventory for no particular reason. Just post a comment somewhere on this site, using a valid Steam-connected email address, and we’ll get a key to you shortly. Bonus points for people who leave real comments, and for people who are actual people and not key-scraping bots. Yes, this truly is the most exciting giveaway of all time.
