When I first joined there were lots of questions about connecting video recorders to televisions, setting up home PCs and connecting peripherals, the sort of pc to buy, wifi problems, using the software.
Now computer equipment is so familiar to all of us and is much less complicated or scary than it was.
There were 'how to' questions about DIY, car maintenance and now we can just watch a tutorial on YouTube and follow step by step instructions about almost everything.
AB is competing with dedicated specialist forums about health issues, parenting, hobbies, crafts, sports, legal problems - if you have a long standing issue or interest I can guarantee there will be a forum for it. Not to mention 'google' - type any question in the search box and usually you will get a meaningful answer.
It is hard to pinpoint what AB is and the appeal to us long term members. I have no idea how to pitch an advert for this site
