Psychology 2.0's key concept is voting, as:

• voting is viewed as an opinion pool that credits the results of a resource-consuming experiment
• when voting, not everybody is equal: based on seniority and professional background people can have different voting weights
• the voting weights are awarded by a committee based on degree, years of experience, special reputation and contribution to the community's work
• the usage of the voting: insert into an article the following markup

(:vote id=1 ask='Do you think it is a
good idea to use the voting for
scientific purposes?' option1='Yes'
option2='No' option3='It is worthy to
try' :)
