I used to be a frequent player on hubdub.com, where you could 'predict' (or bet on) the news. Hubdub sadly closed in April, but I've been considering something on a much smaller scale for a different domain.
My question is - are there any working prediction software clone tools out there that you can easily configure, setup for many users, many topics and scales well? Like pligg is to digg.com, I'm after prediction market software.
I've looked at Zocalo, but it's a bit too academic. Bookmaker has too many bugs open and hasn't been developed in years, and Prediction Market and Betting System are still in their infancy and don't have working websites successfully based on their software as an example.
Any suggestions welcomed, if I have to code the whole thing up myself fine, but I'd hate to be reinventing the wheel...
There is a module for drupal, but the development seems to have stalled. Anyway, from what I have been looking at, there are no viable off-the-shelf open source prediction market products.
