Online photo sharing

Honestly, I was least impressed by this application. Although I agree that Flickr is probably the most usable application, I found the "yahoo pushing" on the site a real negative feature. Account creation is a problem here. I eventually got an account in atpic and used that. I have used PC based photo programs and, combined with email and WEB browsers have found that they work well. However, understanding the "interconnected nature" of WEB 2.0, Flickr type tools are obviously the wave of the future. However, they have to clean up the login issues and curb pushing an agenda on potential users. Just my 2 cents worth.
