Comment 18 for bug 72815

I kind of understand where the original poster is coming from, but I disagree with the notion of making “karma” based on minutes invested.

An action’s importance *does not* necessarily correlate to the time required to complete it. Although this is often the case, it isn’t guaranteed. I also think it would significantly diminish the importance of “low-hanging fruit” tasks—items which are quick and easy to do, but the user benefits because they see the results faster. It’s also beneficial to the project to complete low-hanging fruit tasks because then they aren’t sitting around forgotten while everyone’s focus is all the long, intimidating, difficult tasks. :)

Furthermore, everyone has different skillsets; a task might take you 10 minutes to complete, but only take me 5.

…

That said, I think tracking time would be a very useful statistic to track. I just don't think it should supplant karma, or be the only/primary measure of contribution.
