A Dot-Com Survivor’s Long Road
I've never used Shutterfly, OFoto or any other Web 1.0 photo site.
I learned about Flickr at the first Web 2.0 conference by sitting next to investers, so I was an early adapter and have several cool usernames.
Tagging ROCKS, it was amazing when we first began using Flickr. When I go to a conference and snap a hundred photos I'll find the best shots, crop them, Tag them and put them up on Flickr, but then some other guy snaps two hundred photos, some of his feet and other nonsensical things and then he spames the Tag.
I have five accounts on Flickr because they only let you store 200 photos before they charge you and I can't delete photos because other people have used them on their blogs, so I have a reasonability to keep them up there.
My favorite photo sites today are Bubbleshare and Zooomr, I know the developer-owners of these sites and I can tell you they won't need to burn $90 Million to become profitable.
