Elderelite makes a really good point.
Also, people post about what interests them. A lot of people enjoy fluff. Me, not so much. Frankly I get bored of wading through all the in-jokes and 'kiss the monkey' stuff sometimes (sorry Shamus ). I come here for support and to give support. I know that if a thread is started by certain people, such as Terry, AKJeff, flipper, TD, cedars, Mary, rebel8, 3rdgen, talesin, purplesofa, nugget, sabastious, Lunatic faith, AllTimeJeff (not an exhaustive list, just the first names that spring to mind), then I am likely to enjoy reading it. I go less off the titles and more by the OP.
