Apologies to everyone who has noticed that this site has been crawling to a standstill lately. I’ve been suffering from runaway trackback spam (if you don’t know what that means, nod, smile and move on to the next post). I’ve tried a couple of fixes but have just installed Bad Behavior, which seems to have fixed the problem even without a "u". I was getting a POST trackback.php request once or twice every second which, needless to say, was grinding my server to a halt. This should also fix the problem with the feeds, which should now be more reliable.
Keep me informed by the usual means of any problems that you find.
