Is it just me or are the cookies being a bit tight when it comes to "last visit" time? You only have to turn your back and it updates. Wouldn't it be better to only have them expire when you leave the site?
I use that when the cookies expire, but they definitely seem keener of late. Perhaps they're just working as designed now
Ten minutes just feels a little quick. It's not the end of the world but as I use "What's New" as my primary navigation I probably notice it more that some.
