My answer to a question was recently deleted by Andrew Barber (20K+ member) and I am wondering why. It fundamentally answers the question (although it wasn't the accepted answer) and was also up-voted twice.
Here is the question.
Here is the answer in question.
There are two things wrong with your answer:
I've had to implement my own and open sourced the code [link to code].
First, it looks a tad bit self-promoty. Not terribly, but upon first glance it certainly appears so.
Second, it's what we call a link-only answer: an answer that only gives the questioner a link. The main problem with this is that links tend to break eventually - I'm not saying yours would, but it might. It's always better to have a quick summary with working code in the answer. If you really want to get a link to your code out there, use a comment.
As Undo notes, answers that do nothing but link to external sites are discouraged: links break, making the answers useless, and it becomes extra-difficult to critique, update or enhance answers that exist outside of our system and license constructs.
That said, deleting just your answer was a bit unfair; there were two other answers that ended up being pretty much the same thing - one of which actually does link to a page that's on its way out.
Realistically, the question should've just been closed. Since it now has been, I've undeleted your answer... If you can find a way to restructure the question to discourage the posting of links (and, of course, update your own answer to consist of more than just a link), it could be re-opened; otherwise, it'll eventually be removed.
