I love the new StackExchange dropdown in the header. But what about Area51? Did it get abducted by aliens?
What I've noticed is that Area51 isn't like the other stackexchange sites. Try running some SO greasemonkey scripts on Area51 to see what I mean. All the ones (reputation gain tracker for example) I've tried don't work there, but work on the other sites. That's probably where part of the problem is.
