Oh ya, one thing I forgot to mention is apps such as Tapatalk are NOT compatible with all message boards, i.e. that particular app might not work for your favorite movie board or something. I think forums need to be designed to allow compatibility with Tapatalk, which does seem to be the gold standard for forum reading. Anyway, because of that, some sites like to have their own custom app which would obviously have a good forum reader. FWIW, I'm not aware of a Talk Tennis or Tennis Warehouse app, but then again I haven't looked for one.
