""The demographic of people is different and the subject of discussions ...""
For me, that's a good change.
When I joined it was very much a "Down South", Uni, Career, Mortgage and children late on, in life, forum.
Where I am, in Liverpool and the people that I have worked with, both paid and voluntary, life choices are very different, but just as valid.
I never realised that people who earned min wage were so looked down upon and pitied. Most people that I know are happy to be working, because jobs are few and far between.
Paid bar at a Wedding, not happy to give money as a gift, angst about attending events, no contact until weeks after giving birth, never experienced it in RL, when I've brought up threads to others, they're often in disbelief.
Style and beauty has explained why people from the London areas never seem to look what we would describe as "dressed", even at Weddings.
The site's quality of posts, has risen, since I lurked in 2010, posters are more knowledgeable, you still get the odd stupid question/answer, but not as much when the answer to everything was "get a car/hire a cleaner/doula".
You need a break every now and again, though.
