I came across this question yesterday.

There is two different answer to this question, one has been accepted. Let's call accepted answer answer 1 and the other answer 2.

Recently answer 1 has been edited to include the content of the answer 2.

I don't know what to think about this. On one side I think it is unfair for answer 2 creator because it won't get the upvote he deserve anymore.

But on the other side, as question answer 1 is accepted answer, answer 2's solution (which is better in my opinion) is going to have to better visibility.

I got a bit lost in my explanation, I hope I have been clear enough...

What is the general consensus about hijacking top answer for visibility ?
Is that encouraged ?
