... anybody use it? I think it's pretty good except when their servers go down, the script I had to put in my site's source causes the loading to take forever. This happened multiple times per week and caused me to remove it and stop using their service. Other than that, I enjoyed using it. I am anxious for it to be released stable.
At first it was fine, but then I noticed it happening multiple times per week (at least two) and it would make my page-loading hang for quite a while... So I just took the script out of my source code and I never put it back in.
I tried this out, and didn't have any problems. I reached their 10.000 a day limit and load time was still fast. There has been quite a lot of chatter about this on their support forums and they might have resolved the issue.
