I noticed flickr a while ago and set up an account. Just another online photo gallery, I thought. Now it’s starting to grow on me.
I like the tags system and organizr especially. I’ve only just started looking into the social networking side to it and it’s all done in the clean, intuitive and informal style that you’d expect to find from a site like Google.
I strongly recommmend it. My username is sixball. Feel free to add me as a contact.
