For at least a couple of weeks (or maybe even months?) you would get an error message when leaving a comment on this blog. The comment would still be posted, but that was not clear to the person who wrote it. I did not know what the reason was and had planned to reinstall WordPress in order to solve it. But today unitedstyles CTO Joop Dorresteijn took a look at it and figured out (within 1 minute!) that it was caused by a malfunctioning WordPress plug-in. After deactivating it (30 seconds) the comments worked fine again. Sorry for the inconvenience if you left a comment and were wondering whether it had been lost in cyberspace.
