Lost comments

I apologise that a number of legitimate comments in recent days have been stopped by my spam filters – I’ve just rescued 6 of these from the moderation queue, where I had previously overlooked them amidst 519 spam comments. If you do make a comment which doesn’t appear (and this is most likely to happen to relatively long messages with lots of external links) you might want to alert me to this with a shorter comment. Anyway, my apologies to Brian Wang, Reza Fathollahzadeh, Moderate Transhumanist, NanoEnthusiast, sa. jafari and Michael Anissimov.
