Betting threads have become so popular that they are inefficient. It takes too much time to find the information you are looking for. When bowl season comes around you may as well forget about trying to find any specific information that knowledgable posters may be trying to share.
Thankfully I sometimes remember who posted information so I can go look at their past posts and find it. Even then it's still a hassle.
With a betting board, we can sticky important information, and make everything for our resident TD bettors easily accessible.
