20-25 is fine i think beause you dont read a post more than once so you just skip all the pages you have read and for 56kers
You do read a post more than once if someone else quoted it, you will need to check the conversation he's talking about, at least I just visit the NBA talk section, and there you would need to do that. I don't complain about the time it takes to load and I'm a Dial up 56K user, so if you are going to make the change Andrew, 50 should be OK, that way the NBA talk section threads won't get the break that fast.
