I just posted my first question on SU.
First attempt was vetted as it lacked tags. I understood: better not make a question without tags.
Second attempt with tags: I went through this particularly tough captcha procedure and only after that it my question was vetted as it had too many tags.
Third attempt, I removed one tag, submitted the question, and realized that SU does not yet believe that I am a Human and gave me a new captcha :-(
Is it the way it is supposed to be?
Why not reject my question for excess of tags before throwing the captcha, just as it did when it rejected my question for lack of tags?
I can think of two reasonable scenaria: (i) I am only asked to prove that I am a human in the very last step before my actions are going to produce some effect on the site and generate a new question/answer/comment/whatever; (ii) I am not re-asked to prove that I am Human before I effectively make quite a few question/answer/comment/whatever.
