"Lag, slowdown, and downtime?I noticed the Digg thing is getting a lot of attention, so is that it?"
It was/is Digg. We are getting hammered by their traffic.... dumb me, I had caching turned off! I turned it back on and am hoping it fixes the problem. So if you see any trouble with data you submit not showing up right away, it could be the page is cached for a while.
Thanks for hang on with us through this wild ride. The site has not been up for a month yet and we've been on Digg 2 times and Techcrunch.com once! Whew.
