Which threads will you always open and which will you always scroll past?
For me, I'll always open a money thread, especially anything where the OP lists their monthly expenses. They appeal perfectly to my combination of nosiness and practicality.
"Critique my Rightmove listing" same as above.
"Critique my menu" ditto.
I'll always avoid anything about class (who is middle class, what do upper class people do etc etc). Boring and generally just full of the same stereotypes I could read in Jilly Cooper but with added jokes and sex.
Always avoid anything which involves pretend amazement about how other people do a basic thing eg jam or cream on the scone first.
