MetaFilter has been underwriting TSOYA and MaxFun lately (in part, anyway). I gave them a sweetheart deal because I love their site as much as they love TSOYA. It's totally non-exclusive, but you hear announcements in podcasts about it, and there's a link here on the blog.
I sometimes link to stuff from Metafilter and Ask Metafilter, especially in Blast Processing posts. I've done this since before they were sponsoring me, and will do so after (hopefully there's no after).
I realize this is a bit of a conflict of interest. Just know that they've never even asked me to link to them, the fact that I do has nothing to do with their sponsorship, etc. Honest. If this seems weird (or doesn't), let me know in the comments, because I don't want it to be.
