Encouraging people to explain down-votes
I just posted on Stack Overflow, but due to a slight mistake the system bugged and removed my HTML code from view. I received 4 downvotes in 2 minutes while I was correcting the slight mistake made due to your editor.
I think that's a problem as users will give downvotes, but not take them back when it was the effect of a mistake in clicking a button and it was a bug in the editor.
After answering, I would ask that you use htmlentities to prevent it from removing html and just replacing it with web safe chars instead of suggested correct from post title.
Another Problem and possible fix Users Post down votes when they have answered to try and make there answer look the best,( i have had then even when there answer was wrong)
Make it so if your Down Voting an explination has to be given that way the OP or user can correct the question so it does not get more not telling a users like First User Says some thing, Second user, It's Bad First User, Why? Second User, It just is.
Post in example: can I click one button and use the action of another?
