Nice post! I don't think the money in pool will ever be enough to get fans to watch on that basis alone, but the personal connection to the players is critical, just as you suggest.
Interviews offer players a good chance to come out of their shells, but this opportunity is too often wasted in our sport. As was discussed in the thread posted by Island Drive and indicated below, neither interviewers nor players seem to be keen on letting us get to know much about the competitors, their personalities and what makes them tick. Interviews in pool are plain vanilla time and time again. There's a story behind every player, but the fan rarely learns of that story.
It was such a typical, seemingly unplanned interview that had so much more potential to be great but.............................................. In the 5 minute interview.....they Should of asked him about some of the key shots that got him to Finals. Especially his shot...

Pool also does little to play up rivalries and that's also a negative. I think Matchroom is doing a little better with interviews than in the past, but there is a long way to go if interviews are to become a window into the mindsets, personalities and lives of the individual players.
As you also note, pool players can be a bit inanimate inside the arena, and far too many of them do look a bit robotic. What we need is a little more "Jayson Shaw at the Mosconi" kind of behavior. Jayson often talks trash, winds up the crowd whether the event in in America or Europe, and plays with a perceptible level of joy and exuberance. I'm not suggesting that pool needs a Mosconi-type aura in every event, but the Mosconi reminds us that pool players can be very animated and engaging when they choose to be.
Yes, that personal connection between fans and the players is, as you suggest, something that pool badly needs.
