Web API Directory

[Salamok]

Just saw a link to this on Reddit, personally I think this directory has the potential to be one of the most useful resources I have run across in several years:

Programmable Web API Directory

Within 10 minutes of finding it I signed up for free developer access to the ESPN API that until now I knew nothing about.  I think i'll make a few march madness style bracket web apps, I have been wanting to do one for the Tennis slams for a few years now.
