Sure, although most of the meta has been in regards to fic, not vidding.

This whole things started when kyuuketsukirui posted reviews for the mecshep_match fics and was less than satisfied when them.

lamardeuse saw them and told kyuuketsukirui that she was going to make a post about it. Things got a little mixed up because instead of posting about reviews she made this post about feedback.

kyuuketsukirui responded in her own journal, and metafandom exploded.

I'm a slow reader, and haven't gotten through all of the meta yet, but here are some of the posts I thought were good:
synecdochic: "Cult of nice" vs. "cult of mean", round 2847, fight
xparrot: To crit or not to crit
