For a year or so, I hung out on the sidelines, content with occasional commenting (and carping). I will admit that now that I am actively posting, I have a somewhat better impression. Some of the answers show real expertise. (Obviously I will never be an expert -- not even an expert practitioner -- as I have no qualifications, no relevant education, and no work experience.)
About a year and a half ago, someone started a Poll - how many among the users are "professional" historians?. The results were that no one identified as a full-time working historian, but several admitted to qualifications in the field.
Would it help to improve History.SE's reputation if all the users with academic credentials listed them on their profile page? And perhaps those who are presently posting under pseudonym should consider using their real names instead. Somehow an answer from Joe Smith carries more authority than an answer from flurbugget784...
