Ionut Alex Chitu reports that Google Video recently launched a recommendations feature that suggests videos "based on your search history, ratings and viewing patterns."
My first three videos are all Google TechTalks, which are good recommendations since that is pretty much all I watch on Google Video. The later picks are science videos and other bits of geekdom, not bad either.
It might be worth mentioning that Findory has video recommendations as well, launched about eight months ago, that also uses your viewing history. Findory's video recommendations mostly are for videos on Google Video and YouTube.
Also worth noting is StumbleVideo, a snazzy and easy to use video recommender from the folks at StumbleUpon.
On a side note, I think it is amusing that I found Ionut Alex's post using the related articles recommendations from Findory for this weblog. Recommendations all around, it seems.
