Back in ye olden days, there was the type of kerfuffle about introducing chat as there is now regularly about aibu.
As in "no-one will bother with topics, everyone will shove everything into chat, and it will be difficult to find anything".
Bear in mind that at the time there were probably only about ten topics, and maybe 100 threads a day (in fact you could log in every three days and ask to see "all posts since I last logged in").
When chat was introduced, to avoid people putting everything there, and to keep it for "chat" - as in people chatting to each other rather than looking for advice, or for asking direct questions. It was put at the bottom of the list out of the way. Where it still is.
Where aibu should be now
. Because atm if you hit "last 15 minutes" or "last hour" the first 50 threads you see are AIBU. So most people don't even get past AIBU, which is why tumbleweed blows sadly through the rest of the Mumsnet talk boards.
I remember when it was all green fields around here [old gimmer emoticon]
