#analysis – ICWSM 2011 published the list of accepted papers. ‘4chan..Analysis of Anonymity..in Large Online Community’ (PDF) is interesting for Large Data Practitioners. Folks from MIT analyzed over 5M posts to ‘quantify ephemerality’. Median life of a thread is ~4min; longest lived thread in sample was alive for only 6.2 hrs (think that w.r.t. identify-enabled sites). The authors found ‘anonymity promotes disinhibition, mob-behavior’ but the disinhibition worked better in ‘advice and discussion threads’. NSFW language warning for contents reported verbatim from /b/ or 4chan in the paper.
