I joined WIWIKAU a number of years ago and found it interesting at first. Now I am just waiting for my youngest (graduating this year) to be done and I'll be out of there! It started off well but as a discussion group I think it's just completely unwieldy and repetitive now.
No one seems to be aware of how to use a search function or even bother looking back through previous posts, and the same questions about what to take to uni, what should go on a personal statement, what deadlines for various things are, et cetera et cetera keep coming up over and over and over again.
Even if you've never had a child go to university and you haven't been through higher education yourself I can't understand why people think that they should ask their question about a specific university or moving in dates or student finance questions on there, rather than at least making an effort to look on the SFE website or the University website or whatever first. It very often seems like people expect everyone else to do the work for them. Facebook posts also don't lend themselves to laying out answers in a coherent fashion. Very often, you will get a bunch of answers to a post asking which university?, Which course?, Or something along those lines, and once this is clarified by the original poster somewhere in the middle of the thread, the targeted answers get hidden somewhere in the middle of the thread and keep being answered over and over again by different people.
As people have mentioned, there also seem to be a huge number of parents over there who are completely over invested in their child's university application and time there. The amount of headspace some people give to bed sizes, en suites, kitchen cupboards etc is mind-blowing. It's like they have to micromanage absolutely every aspect of the application and university experience.
