My waits in the queue when I've gotten it haven't been terribly long so that isn't a bother other than my belief the capacity should exist to a level it shouldn't be needed.
What I've been noticing though is that once I've signed on I tend to stay signed on for longer than I have in the past. I wonder if they might have established a routine of not logging people off after some short established time even though they are still active on the site but will search and bump off users who have been inactive if there are people requesting to access the site?
