Well although I read YD via 'New Posts' I use the 'DIR forum' tag as a marker of somewhere where I should not reply to questions as people are asking for a distinctive style of answer.

Now we accept that YD is a hunting ground for DIR to try and attract new converts to its fold but those of us who have passed beyond that would prefer not have it quite as 'in-yer-face' as abolishing their own little enclave would make it.

Similarly rebreathers need their own bolt hole. If I want to discuss alpinist solo decompression techniques I want to do it somewhere without giving offence to sincerely held beliefs.
