Just one point! You may find it easier to browse those that have Chat enabled. This rule is not uniform, but in my experience it does seem to improve browsing if they do have it enabled. But you can still browse some that don't have it enabled. It is more effective when browsing those that are uplding from you. If they have chat icon listed next to their ip then chances are you'll have a much better chance of browsing them. But to reiterate, deepblue's initial response explains the rest & ursula's comment it's often more difficult to browse dial-up users.
