Around bbs there are some competitions that i am part of the people that say that it should be a little more specific. This is for a easy reason, the ambiguity turns into something against the quality if users do not know what exactly they are looking for to create.

weekly competition about a good post and the concept itself about a good acount are things that are not clear for everyone, every one can know plagiarism,spam and similars are bad things .

Interactions about what they see as something good, are related more specifically (asumptions) :

-Post that creates tips or mobility between users

-Real interacions with comments that counts as that for the 10 seconds timer after you comment.

-Variety of acounts/users that makes interactions

-Maybe the trust in the system trhough the use of things like tips.

Do you think in something more ?
