There was another thread on this (actually several). The BF staff/ownership doesn't like something about Tapatalk and won't be using it. They claim a security issue, my guess is that it has to do with advertising.
They did claim that they were working on a mobile app or version of the site and that it would be out before last Christmas...well obviously that didn't happen. Tom has been claiming that they have been working on it since 2010. Um...it just doesn't take this long to write software these days. And IMO is foolish to duplicate work that has already been done...WELL.
