Hi Alan,
Interesting question. I usually go to chit-chat, then UK parks and then overseas. I will also go into anything with new posts to see if I've missed anything.
Chit-Chat is great, it shows that us caravanners have a good sense of humour and you can usually find a joke there which I haven't heard before, or maybe I should just get out more!!
I always look at the UK and overseas parks to a)see if there is any parks mentioned that I have been to and b)to look for recommendations for sites.
