Really? I haven't experienced anything out of the ordinary load time. But if others are having the same problems, maybe whoever takes care of the server should take a look at it.
I do use Firefox, and my internet connection is fine. The problem is, most likely, as you said, that I usually am online when the servers are the busiest.
I have been having issues in load time of pages, but other sites are loading just fine. Of course I do tend to be on during busy hours. Thanks for letting us know that this is happening, it's hard to know if it is just me or the site without people informing us.
