I noticed some quirky behavior in my website after I installed Google Web Accelerator, so I put danpremo.com in the “don’t accelerate these sites” list.
I noticed the issue during the following: I created a new post, saved it (and continued editing) a couple times, then published it. Immediately, it was still in my list of unpublished posts. I clicked on “View Site,” and the front page did not have the latest article. So I put it in the DATS list.
