I think as time goes by I spend less time on the board. If a thread comes up that has already been done before, I skip it all together or just read the first few posts. If someone asks for help (which border fabric should I use...A, B, or C?), I post my preference but I don't read the other 5 or 6 pages. I rarely read the recipes (I don't cook) or the section with quilt shows and happenings. Sometimes I scan the for sale section but not regularly as the last thing I need are more fabrics or patterns.
In other words, I guess I edit my reading. On the other hand, I look at all the pictures. If I am having a night of insomnia with lots of time on my hands I may read items I skipped over previously.
