Photo Sharing Site?

Any one know of any good photo sharing sites? I don't like photobucket too much...it messes up a lot and seems very commercial, if you know what I mean. I currently use Zoto, but its very slow if you're looking for a specific picture. I have 300 pictures on there and to try to find one is h*ll. I like to have an album and also be able to direct link onto other sites, too.

What do you guys use?

I use zoto for my pictures and photobucket to load my signatures. :)

Flickr people can leave comments on your photos and you can join clubs too.
