It's not April 1, I can think of many other people who should get that before me...Miserable user....
Cache is on. Just wanted to let you know about the hangup with skimlinks. Seems to have cleared up now.It's a yahoo provided javascript API file... It's used on many websites... but it should be cached (meaning you only need to download it once per session at most) - are you running with a browser cache turned off?
In any case those kind of things usually clear up themselves.
