I am going to answer my own question, with my thought on the matter.

I think we should try, when possible, to keep the answers here instead of on Stack Overflow. Since we now are in open beta, we can link to answers posted here to avoid answers by different people on both questions.

Ideally, this should be posted as a comment, to the question. This would also help us promote the site to the users that hang out at the drupal tag on Stack Overflow, which has been discussed already.
