I've been here on and off since 2012 and some things have changed but that's going to happen in a decade.
There were always complaints about how nasty posters were and how it used to be so different and it was never massively different. And posters always have someone or something to blame for MN being shit at times and seeming to get shitter.
It was penis beaker, then MRAs, then the Daily mail, the TRAs, name changing, Americans.. Truth is, a lot of people just like a fight and to be unpleasant online.
I never saw a wealth of hilarious threads. A handful maybe that were quite funny. One change I have noticed is that you didn't used to have to say you were joking or being 'lighthearted' as most people generally got the jist. Now even if it's states lighthearted, people still jump on to take offence and attack. There did used to be at least some sense of humour.
An excellent example is a post a few weeks back from someone very obviously being tongue in cheek asking if she was U to be offended that when she buys wine on the self-service checkout, the worker comes over and only glances as her before pressing the 'clearly over 25 button'.
And received replies along the lines of 'get over yourself, they're only doing their job, "well you obviously look over 25, stop being so vain" and several people ignoring the AIBU completely to instead make comments implying the OP had a drink problem because she posted a thread about buying wine and the time she posted was around 9am 🙄
I think that's another thing I see more of than in the past. The posters who ignore the majority of the OP to start being bitchy about an irrelevant detail. A poster can start a thread about their DCs school anxiety and get a bunch of snarky orthorexic comments about the fact they mentioned their DC had cocoa pops for breakfast.
