<p>Cross-validated is a good site to sharpen one's skills in statistics. Lots of teachers and learners switching roles constantly, almost like taking a seminar. Today, someone said he is just a newbie and he is glad to get my help and attention, and yesterday a guru told me (I'm paraphrasing), "Well when I was a newbie (like you), I had people throw rocks at me too." So, it seems there are layers of newbieness. So maybe this is a question for the "great ones" on the site, "When did it occur to you that you weren't a newbie anymore, and how did you know that?"</p>
