Description of problem:
This is just a wild thought that if we could get a "Like" button against each comments, would be nice to have. Sometimes devels, PMs and QEs or any other commenters not just provide information on issue or fix, some provided information is equally good to like (express a special feel).

And There are many tasks or comments which are worth helpful or an achievement. So, it would be good if respective person gets some credit based score (like Karma), given by that or those people who feels its helpful or an achievement.

I am not sure how feasible, easy or difficult to implement it, or if at all feasible or good idea, so, putting it as Feature Request form.
