Reading around on meta you realize that downvoting here is not the same as on stackoverflow.
Downvoting is quite more "subjective" as many questions here don't deal with technical problems, but instead deal with discussions that can be related to quite a few topics.
A Stack Overflow profile is a professional representation of yourself.
In the same way, your Meta Stack Overflow profile can be taken like that by some people as well - who may not be informed or know exactly how Meta works.
Apologies if this has already been discussed somewhere else; my main point is that connecting downvotes or disagreements to reputation causes reputation to be affected by popular subjective opinion. Doesn't look good to see a question or answer with -20 to someone who doesn't understand Meta.
My question asks three things and states one last:
Should reputation by connected to downvotes
If reputation doesn't mean anything why have it? Was it supposed to mean something else but since many are not happy with the way things work they say "ignore it". If something is broken just ignore it?
Could rep penalization fear lead to people being wary of contributing?
Finally, negative reputation on MSO could be misinterpreted outsiders.
