Popular video aggregator Hulu, which says it now has roughly 900 titles from more than 100 providers, has added genre-based channel browsing to its list of features, as well show recommendations, discussion forums and actor-based search.

The site debuted 17 new genre-based channels, among them action, comedy and horror. Meanwhile, Hulu launched an anime channel with shows like Naruto and Death Note, as well as a “Web Originals” channel featuring such high-profile shows as LG15: The Resistance, The Line and Gemini Division.

Hulu has also added show recommendations, though they are inconveniently buried way down at the bottom of the page beneath the new show and episode-specific discussion forums. The actor-based search works as you would expect it to; a search for “Tina Fey” brought up 30 Rock along with red carpet interviews, and results were broken down by TV network.

Rival online TV service Joost recently ditched its download client to become more web-based like Hulu, and added more socially oriented content discovery. Hulu will be making its own leap into deeper social functionality when it rolls out its Facebook Connect integration, which was supposed to launch in August.
