Someone just sent me an invite to a site called Ringo. It appears to be a "share photos with friends" site and it obviously aims to grow virally: it looks like people must sign up before they can see your photos, and when they do, they're encouraged to upload their own photos to share.
The site is hideously bad. Pop-up windows abound, and they're the type designed to get around popup blockers. Flashy, blinking graphical ads. Ick.
While I appreciate other people putting their photos online, I shant be using Ringo to share photos in return. At least the people at Flickr have a clue (why else would Yahoo! buy them?). Even without Flickr, which I'm saving for my better photos, I at least have my own hosting, plus there's LiveJournal's Scrapbook, which I'd use if I had the patience to learn S2.
