I recently answered a question asked about 3 years ago, with almost 6k views (and growing), no accepted answer (the asker left the site apparently), and 4 existing answers with upvotes (but as far as I can tell none of them is a conclusive answer to the question). Mine is not conclusive either, but I honestly believe it's useful to people who are facing the same problem. However, being a (very) late answer, I believe nobody will scroll down all the way there, despite the fact that it's still an unsolved and recurrent problem.
Since my answer has things in common with the most upvoted answer, I thought about commenting on it to draw attention to my own, but was unsure if it was fair to do so. On one hand, it "feels" like a d*ck move, worsened by the fact that my answer involved self-written code (is it really a good contribution or am I just flattering myself?), and the practice is ripe for abuse. On the other, the ultimate goal of this site is to provide great answers to important (to its target audience) questions, and nobody wins anything if a potentially useful answer is obscured by circunstance alone.
I could just follow my gut and do it anyway, or simply adopt the "safer" alternative of including my whole answer in the comment, deleting the original, or even offer a bounty to the question in the hope someone pay attention (despite how silly it is - attempting to reward my own answer knowing the system won't let me). But I was curious about what the community thinks about this, in the general case, so I decided to ask here:
Is it ok to comment on a better voted answer to draw attention to your own?
(P.S. in case someone think this is a stunt for self-promotion, consider this: if my answer is really not useful it's easy for people to downvote it to oblivion... :P)
