It’s one thing to talk about how Web 2.0 – or the “Dynamic Web” or the “Live Web” or whatever we’re calling it today – allows companies to start and even grow to an extraordinary size with a little ingenuity, some open-source tools and some moxie, but it never ceases to amaze me when a new one pops up. Thomas Hawk has a great post about one called Zoomr.com, which is an online photo-sharing service kind of like Flickr – which as we all know was started by a Vancouver couple (who appeared recently on the cover of Newsweek) and was then bought by Yahoo.

I got an email from the guy who started Zoomr a little while ago, and checked out the service, but I have to admit I wasn’t all that impressed. Great – another photo-sharing site, I thought. It has some features Flickr doesn’t have, but I didn’t think it was anything special. In fact, when it comes to Flickr competitors, I think Bubbleshare.com (another Canadian startup) has a lot more going for it. But then I read Thomas Hawk’s post, in which he describes how Kristopher Tate, the 17-year-old who started Zoomr.com, added a new feature while he was talking on the phone with Thomas.

“So while I was chatting with Tate about trackbacks at 10:32 a.m. this morning he wrote me, “yes, one big thing that I want to do is a sort of photo “trackback.” We then chatted a bit more about it and at 10:53 he wrote “Hmm, I think I’ll add the trackback feature in now.”

And just like that, trackbacks or refers were implemented. A feature that Thomas Hawk and others have been waiting for from Flickr.com for months, but which the larger site can’t implement because it is wrestling with integration of its servers with Yahoo, and so on. Yes, Zooomr.com is just another competing photo site, and yes it probably suffers from the same deficiencies as far as a business model is concerned that many other Web 2.0 companies do — but damn. That is cool.
