Just a quick note re: comments. Recently this blog has been attacked by spammers who copy existing legitimate comments and re-post then; their user name is a link to a click-harvesting web-site. I am doing my best to mark these comments as spam and not allow them.
Besides that, I am likely to nuke any comments that contain profanity, spam, repeated requests for tech support via the blog, and off-topic comments particularly on posts that have are meant for a narrow discussion (e.g. global scenery defects).
