Mine probably loads slower than most because I max out the number of posts per page, and one of my most frequently visited threads is Badge Trends, which is heavy in pictures. Put the two together and it's not super fast (mostly because of all the images loading from various sources)- but GC itself is fine, and seems like lightning when I load non-photo threads like this
As a side note, I will say that many people have been confused about how to post pictures. Not sure if there's an easier way to do pictures here, even to upload them straight to GC. But then that'd get into storage and retention issues, I know... but a girl can dream, right?
