I think you guys keyed in on the 4 main reasons for the lack of numbers.
1) It was set up for 200 or so spectators, even the WPBA events (at least the one I went to in Mt Pleasant) only had seating for 200 or so, so while it would be nice to set up a venue where 1000 people could go and watch, it would be a logistical nightmare AND a huge monetary gamble.
2) The length of the game. While it might take ALL the 'lucky rolls' out of the game by running to 100, it also takes out all but the most dedicated pool fans/gamblers/people with NOTHING going on for an entire weekend. Maybe shortening the race to 15, and running first to 4 sets would be more attention grabbing, or having a king of the hill type tournament where 4 or 8 players post 2.5k each would be more appealing, racing to 21 or 25.
3) Advertising... I'd have NEVER known about this match if it wasn't for AZB, and I have many friends who are much more serious about pool than me, who had no clue it was going on. the Johnny/Earl match has been advertised a little more, but still only within the pool community. Being from england originally, I know that the OTB companies are the ones who profit the most from sponsoring snooker tours and tournaments, why not get a casino involved, really ramp up the ads and create an environment where average joes will put down $40 on one of them to win.
4) Production quality.. As much as I thank JCIN, runout media and the like for doing what they do, and it's got a charming, grassroots feel to it that you can't fake, it's also a huge negative. I doubt they'll be hearing from ESPN2 to show a selection of the top 10 racks from the match (which is almost criminal.. the drama, the phenomenal shooting of earl, the epic table would make for great TV). Obviously someone at ESPN thinks that the WPBA is more Television friendly, whatever the actual case may be, the pool players/pool organizations can't be stubborn, there has to be a middle ground between the network sports companies, and the big names in pool to find a TV friendly, authentic product that can be produced.
I just feel like the streaming video pool isn't going to be the breakthrough in pool that some people are hoping for. It's a treat for us that love pool enough to hunch over a laptop for hours watching a match, but we're in the minority. I personally think bringing the men and women together, along with top amateurs from qualifying tournaments around the world (Just like the WSOP does) and running a week long tournament, then televising it in weekly installments, with back stories and great production would be phenomenal, just remember, Texas hold'em didn't have the growth it did, until Chris moneymaker shocked the world. Imagine if Jason Kirkwood or Adam Smith or Hennessee hit that gear they have and ran through appleton, corr, immonen and hatch before losing to ouchan in the semi-finals, and getting to watch alex/jasmin in the finals...
PS. I know this was tried before, with the Tavern pool championships (or whatever it was called) and the huge tournaments from a few years back (forgot the names of them), but getting television coverage and a channel like ESPN and a casino involved would make running it so much easier.
