Posts about adverts are controversial on Metafilter. Some people think adverts are ok. Others find them intrinsically distasteful. Mystery meat posts that turn out to be 'hey look at this great advert' and nothing more can lead to derails and nasty arguments over whether or not using Metafilter to spread advertising in this way is acceptable or not. Accurate tagging of such posts with 'advert' or 'advertisement' could avoid this. [more inside]
I may be missing something obvious (checked previous metatalk queries) but this post has an advert in it shown in Firefox but not in IE. The advert is for www.ecological.co.uk. Is there a reason for it? I don't remember an adverts on/off feature.
