Do you think that SW should have a down vote and up vote system?

i think that feature would be abused by sad losers with no sense of humour who are easily upset by those who have intellectual prowess.

No... it's still got some of EP's "support site" DNA, I think downvoting would run contrary to that.

No, that makes sense on a content aggregator like reddit but that's not the purpose of this site.

yes i've wanted to minus heart some posts

No, that would only create more drama.

Yes.

After everybody is allowed only one account.

The only time those up and down likes will count.
