I'm a very recent (2.4.4) convert to LimeWire after using BearShare ever since Napster died. In both services, it was possible to browse the libraries of people who chose to make them available.

From the upload requests I'm receiving it appears that the same thing is possible here. Granted, I think LimeWire might have more users than the other services but I can't believe that that many people are searching for some of the obscure mp3s I have without being able to see my library. Am I just imagining this?
