I recently answered a question which was promptly deleted by a mod, I realized now. I know I am new in this site, but I have been a long time user of SE sites and I think this decision is flawed. Here's why:
First off I think my criticism is on point. Those of you who have been a SE user for a long while must have seen your fair share of such questions. They don't age well. This has been discussed over and over again..
Secondly, the answer actually addresses the shortcomings and potential pitfalls, with relevant examples.
Last but not least, I did finish off with actual advice which answers the question.
By deleting an answer like this, you are essentially making it unaccessible for new users as well as the OP. It's not like I could have fit all that content into a comment...
I think this is a case of overzealous moderation. If it was SO where you get thousands of questions, and many useless answers, I'd get it. But for a site in Beta, I think it's a bad idea.
