I'm not putting this in site stuff because I'm not addressing it to HQ, I'm addressing it to people who've used the site for a few years. By oldies I mean people who've been around for a bit - maybe a couple of years?
For me - it's still that they will NOT housekeep AIBU so that the site doesn't look like nothing but AIBU for everything.
Some people post really serious stuff in AIBU (paraphrasing but AIBU to be upset at this devastating cancer diagnosis/violent relationship/being made homeless/dire poverty/dog poo on the streets/state of the NHS/genocide in x country/shall I abort or not) etc. There is nothing unreasonable about what they are posting.
I've moaned about it for years and years and, yes, I'm still here - there aren't many alternatives and I enjoy the food, travel, S&B, TV, property and chat boards and have received and given loads of useful info over the years. But I probably missed a lot because threads on those topics were posted in AIBU.
And also, I think outside of Mumsnet it makes us a bit of a laughing stock.
So that's my biggest petty gripe. What is yours?
Bonus 100 points for every "if you don't like it you can fuck off" post.
