I really like theoldreader because it was a zero-overhead switch from Google Reader (and I liked things about Google Reader that were changed in other alternatives that I briefly looked at).

However, I switched to bazqux.com a few weeks ago. It has all the same Reader features I love, but also shows comments, which is a great feature addition. Oh, and it feels lightning fast. They charge $9/year and will probably never get overloaded since they have the worst site name ever (from a marketing standpoint).
