The addicts among you will have noticed that the sidebar for my blog died in a "it's been replaced by an error message instead" way. Whoops.
This was all due to my lack of foresight that people who have Irish names might post comments on my blog - the offending name was "O'Riley". Problem with this being that I also use ' to contain strings and things... so when the PHP thing saw 'O'Riley' it assumed that I was quoting 'O' and that Riley was a load of crap that it didn't understand.
I've fixed this now :-)
