I'm on dial up so they are painfull!!!...that means often they don't even down load, and I wast a lot of time waiting for down loads I don't necessary want to see.
Problem I have, I can't afford broadband, and with family, job and other committments I do not have that sort of time it takes to down load and refresh pages.
I thought the size was fine, may be a little bigger, but not the size you have them. Otherwise it may be that you reduce the number of posts per page, so people don't have to down load a lot of stuff they have already seen (as a regular)
