I use it several nights of the week, and I find that it gets old real quick if it's always there... I find bringing it out every couple shows keeps it fresh... also, as for the data mining.... It's actually illegal to send unsolicited text to phones which is why the text live has the subscribe function. you will find that teaching people to subscribe is a pain, and very few would do it anyway, because it's costing most people to receive that text. I initially thought it would be great for that, but the more I read, the more I found out how much you could get in trouble should someone decide to report you to the cellphone provider.
it's almost akin to placing flyers in people's mailboxes...
I use text live for fun, and actually find it's most useful for my karaoke contests...
I'll be running it tomorrow for all the fellas out here at the name convention to let people see what it's all about...
but like I said, I think that the novelty wears off in a smaller bar... now on the weekends, it's non-stop texting due to the sheer volume of people, but on the slower week nights, I find it often ends up being the insult board, or a game to see who can slide the most foul message past the offensive words filter...
all in all It's a great supplemental tool, but as for an event in itself, I don't know...
if you spruce it up and run music videos, or crowd camera, and other things like specials, or slideshows with upcoming events and stuff, it definitely becomes multi purpose...
