That's an easy question with only one answer....the internet.
Think about it....all the marketing of magic shafts, tips, chalk, etc.....the sales of this stuff would take ages longer without the touts on the web.
The action reports, knocking, tournament results, more knocking.....and never ending replies about what you need to make a ball has provided the unwary surfer with tons of bad...misinformed...my way only...type of info.
It's bad enough going to the pool hall and asking a few questions....which might or might not point someone in the right direction. But cyberspace spots all that the last 6 and the breaks.
