Dear list members, in the course of researching for my master's thesis on image board culture (think 4chan, LOLcats, Rickrolling etc.) I have been trying to find literature describing a typology of internet forums and forum- like precursors (BBSes/USENET/...) with respect to formal properties such as moderated vs. unmoderated, anonymous vs. pseudonymous vs. real names, distributed vs. centralized and so on. Even though I put quite some effort into finding literature, I couldn't find anything even closely approaching a comprehensive overview/typology. In fact, the wikipedia article on internet forums was as close as I came. Can anyone here help me out and point me to relevant sources? Many thanks in advance! Best regards Nils Loeber
