How about participants with the best posts being asked to be facilitators next TechniCity?!

Would be awesome from a cultural perspective, having people all over the world communicating!

Rewards for quality could also be - people to follow based on quality of info - not number of posts.

I feel that a number of people with 'high scores' have been recipients of rewards and their quality of comments is in some cases 'spam' - architecture, new iPhone cases, all about the one same theme that is a bit off topic and things that not technology to get a prize..

Having a user return to a platform and engage in our days is a tricky game. I feel the incentives would benefit from altering towards quality not quantity..

Happy to talk further
