Loopt is an awesome service, and also not "just" a website. I have no doubt they'll be successful (assuming they execute), but the potential isn't nowhere close to Xobni's. Every Internet user is also an email user, and email is a mess. Big and hairy problem to solve, but I like how they pick which little pieces to bite off first. Another YC startup I like a lot is Webmin: problems they solve are very real and I like their OSS approach. I use both webmin and xobni myself. However, the point I was trying to make was that most valuable businesses that YC funded ARE NOT just websites, they actually do some heavy lifting, because too many guys here are too fixated of becoming next Reddit.
