Flickr-
I found flickr originally abit hard to use, having to create a yahoo account annoyed me because different email accounts everywhere with different passwords is frustrating. What would be good is if flickr could take an existing account (like facebook can). I can see how people would like flickr as is similar to myspace in the fact that it is about photos etc. But when you can post photos on a blog there isnt the greatest need to have several different sites when one can do eveything. With sites that everyone centralises to like facebook and myspace, the need for flickr isnt imperative.
