I just had a response in a question thread deleted because I said "Thanks" for a well considered response. The issue I am discussing regarding a knowledge wiki for basic, constantly repeated answers is appropriate. Having the post deleted is like a slap down. Very rude! The comment by the moderator is appropriate, the act of deleting the entire comment is a real turn-off/put down to someone new trying to participate on the site.
It has been deleted because it is not an answer to your own question; it could be a different question, but it's not an answer to your own question. The fact you started with "Thanks kiamlaluno," made it seems as you were replying to me. In your "answer" you then say, "Please let me know if you think such a resource makes sense here at Drupal Answers." which makes it another question altogether, as you are implicitly asking "Do you think such a resource makes sense here at Drupal Answers?"
SE sites are not forums, and answers are not threads; this means there isn't a continuous feedback between who asks a question, and who replies.
In a forum, a user would wrote a post, somebody else could ask a question to which the OP replies, then the other user could answer to the question asked in the post, the OP could say the other user is still not understanding what he is asking, etc. on SE sites, including meta sites, you ask a question, and you get an answer; if there is something you don't understand in an answer, you can ask that in a comment for the answer, but if the exchange of comments become too long, you get the suggestion to continue the discussion on a chat room appositely created, as comments are not thought for discussion.
