It used to be I would read every post on every thread. I'd fall behind during the week but catch up on the weekend. (It is my impression that people post more frequently on weekdays, but I haven't bothered to check.)

These days I "subscribe" to threads that interest me and concentrate on those.

But I also scan the "Last Post" column for familiar names. If a friend has posted on a thread it might be worth a look.

I seldom look beyond the third page of threads, because I've already seen (or ignored ) the older threads.
