Thanks to Fred's tweet this AM, I spent some time over at Songkick today.
At Songkick, you can create your own personal "gigography", import your last.fm profile, add concerts, update information / provide commentary about concerts, set a tracker to see when artists you like are coming to your area
- basically it's a way to broadcast your concert going history by claiming "I was there"
My own personal concert-going history is now being memorialized at my Songkick profile page. Yes, Boston, Poco and the Doobie Brothers was the first show I ever went to.
Not sure how useful it will be going forward, but it is interesting to see what concerts they already have in their database. Even shows at Lupo's in Providence I had long forgotten about were in there. Interesting.
