So I went to a question I had an answer for and noticed that the op had already voted an answer as being correct. The particular answer had a list of links.
So I thought to myself, wouldn't it be better to have a more complete correct answer instead of having more smaller answers? In other words, instead of adding a new answer I edited the correct one and added the link there.
I find it better for two main reasons: a) the correct answer would be more complete and b) I am not looking for votes, any votes will go to the guy with the correct answer.
In case it matters, the question was: Getting started with Constraint Programming
