Ask HN: Favorite site for finding new js libraries, frameworks, db stuff, etc?

I used to love browsing del.icio.us for jquery plugins back in the day and love http://www.functionn.in/ but he hasn't been updating it much lately.

HN is great but all the industry insider stuff is a time sink for me and I'm trying to avoid using the computer unless I feel like it's for something productive.

Do you have a favorite go-to site for finding cool new programming and design tools?
