Academia.edu is a sort of facebook-for-scholars, but without the game invitations and image macros. The site allows academics to post their credentials, articles, research interests, CVs, and other details in a forum that is far more accessible and amenable to social networking than the institutional pages that some academics get. Most graduate students and independent researchers have no other way of making their presence known on-line outside of these sorts of forums. Some people on the site post questions to the general readership and one of these got me to thinking. That was a while ago, and this entry took rather longer than planned. This is aesthetically appropriate considering the nature of the original question.
