i've never seen a babynames thread deteriorate into a netiquette debate before, but it's quite entertaining in an odd sort of way!
anyone getting angsty (yes i know it's not a word) and trying to check 'rules for posting' (lol) needs to remember that unwritten rules of different forums (ie use of txt spk, or poor grammar and spelling) are just as important as the written ones (no personal attacks) in order to make using a particular forum a pleasurable experience for all.
and the poster who used learning disabilities as a retort should be ashamed. there are many posters on mn who use various forms of technology to enable them to post (said technology introduces spelling/ grammar issues due to the nature of english language), and if anyone dares to correct their posts, the wrath of mn descends.
generally speaking, the correct rules of netiquette require lurking for a bit to work out how not to irritate people, or at the least a read of the boards to see how others post. i have only ever seen hun etc used in a derogatory manner (or as a reference to netmums or (gulp) the pushchair threads) and as a result, never visit either. in fact, in mn classics there's a, well, classic thread which was a result of a 'visit' by some users of the netmums forum. many of these issues were lengthily debated there...
anyway, fascinating what happens when two different aspects of mn collide.
