Actually I am having this problem too, just that I thought the problem was on my side so I didn't care much about it... Just reload the age and I will get it...
Meh, now that my internet is down, it seems as if this is the fastest site compared to others, being on dial-up. Though before that, yes, there are times where there's like a network timeout, however, a refresh fixes it.
Not only is it slow at times, but sometimes when I try to post, I get a strange error. Apparently, I'm not the only one, either, as a lot of people have accidentally double posted because of it...
Not necessarily slow but some type of problem comes up when I try to get on sometimes. I use Google Chrome primarily now and sometimes i get this 500 something error.
