Microsoft recently tweeted some stats about developer uptake since the BUILD conference, and overall they're pretty impressive. There have been an average of 1,500 new developer registrations every day since the conference, and more than double the Windows Phone 8 SDK downloads in the first 8 days compared to the 7.1 SDK.

That works out to a 17% increase in the total number of Windows Phone developers out there, and makes the WP8 SDK the most rapidly-downloaded development kit Microsoft has launched this year. Of course, this all might have had to do with the significant slash in registration cost. We'll have to wait to see if there's actually an increase in apps available.

Any surprised by these numbers, or at least impressed? How many devs here went to BUILD? Did it pump you up to get working on Windows Phone 8?
