You know, I wonder if the "shout box" might have something to do with it--but for the record, I'm neutral or indifferent about the "shout box," which seems to be both popular and unpopular.
I'm on wireless, Windows, and Explorer, if that means anything.
When I first log on, conservativescave seems to not go, not start, for a few seconds, and from appearances (which might or might not be deceiving), it seems it's because the "shout box" is loading.
After that, I zip and zap through the site speedily and effortlessly.
It's not a big deal to me, but it is noticeable.
