If gambling is another activity that you enjoy to do in conjunction with pool that is great, two birds one stone. I have met alot of people in my time that will not bother to screw there cue together unless there is money involved. Trying to get a friendly game and having the reply be "lets play for five,I gotta have something on the line" is a little ridiculous. If the possibility of winning five paltry dollars is enough to force you put the screws to it you may want to rethink some things. Just saying. Not that I'm painting anyone in this post with that brush, just an observation in general.
There are some positives for pool in general. On a global level it is bigger than ever. In England, China, the Philippines it is mainstream or close to it. There seem to be more high profile tournaments than before. If this trend continues,I think we will see a much more mainstream acceptance somewhere in the future. If people in the industry could get out of each others way. I just don't see gambling being the big factor there though.
