From the Management:
Occasionally users have problems commenting on our blogs. This usually happens when the system is experiencing a high load (i.e., lots of people trying to comment at once). This would result in a "500" or "Server Timeout" page being displayed.If you see this -- take heart. Your comment has most likely been successfully submitted. If you hit your back button and try to submit it again, more often than not it will result in a duplicate comment being submitted.
We're always trying to make the server faster and more powerful, so we apologize and appreciate your patience when errors come up. If you're seeing a different error, feel free to email it to us. We'll see if can track down the source of the problem.
Sorry for the inconvenience.
