This is interesting: a. Developers on average are probably low on E trait in the Big Five b. Most users in the online developer communities (at least the ones who will be doing the "social" part, per the standard 1% rule of social platforms) loathe LinkedIn-style stuff, being asked to log in or provide PII. c. Most "social" services devs regularly use are for technical/utility stuff (GH, SO, subreddits) more than the social aspect.

If a, b and c are true, then this site is reinventing HN/proggit with forced GitHub login on top. NGMI.
