Well, when two sites offer the same features but one offers OpenID and one doesn't, I'll be a little more wooed by the one /with/ OpenID. But then again, maybe I'm not your target audience. ;) My use of Ma.gnolia over Del.icio.us illustrates this. I guess the main idea is that it can't hurt to implement OpenID, it can only help your service. You can still ask your users for all of the data you ask for during a normal registrarion, but /you don't have to/.
