Yeah, there was a project comparing YT comments with Metafilter comments at one point:

Looks like the latest comments are from Feb 2015, sad that it's not still live.
Not a terrible quality snapshot though.

Metafilter's highly underappreciated.
Sometimes I think that's a good thing.
YT comments should have been hauled out and shot. Not jackboot-forced onto other platforms as well.
