Hey! That's my site (m00d.net) unfortunately minecraft.net had about 90% uptime a few months back it screwed my poorly built application, without error checking it filled the db with junk so I took it offline and never brought it back. Mojang told me that they liked looking at the data so I expected they'd throw their own online, a more accurate one.

I'm considering talking to them again and seeing if they'll provide me a dump of sales data (just the timestamp of purchases) so I can re-grapgh everything, it would be cool.

I don't have the raw data but I have checked the stats page every week or so during the last few months. Minecraft consistently sells around 9,000 copies per day. I also got the impression that that number grew from around 8,000 to around 9,000 during the last months but I could be wrong about that. That rate of growth doesn't seem to grow anymore but it also doesn't seem to shrink. 9,000 copies per day at 15€ is a huge amount of money.
