Changing Tables

I find that ,when I'm playing online (of which I've been doing more lately), I'm changing tables very frequently. I keep two or three tables going at a time, and in the open corner, I have the lobby. Anytime there's a break in the action, I check the lobby for new games, or better games with short wait lists. There are even times when I play a single orbit before changing to a new table. Does everybody change tables this fast?

I also find that great games (high VPIP / pot size) with long wait lists tend to tighten up by the time I sit down, and I have to find a new game almost immediately. Does it also work that games with small pots get better?

One more thing, I've noticed that new games online are incredibly loose, and quickly become the best tables, before tight players notice and attempt to sit down.
