Consider these wise words from Lachlan, who recognises the thousands of hours reviewers and editors put into the peer review process.
"...what if there was a peer-review currency, which we call 'Karma', earned by doing timely review and spent by getting manuscripts reviewed. If every academic did as much peer review as they demand from others in order to maintain a positive Karma, the system would become self-regulating."
Lachlan Coin, co-founder of @PreprintSpace (formerly Academic Karma)
