My target audience is quite broad and from what I can gather (just by evaluating the communities themselves, not directly engaging individual users) they _most likely_ have social accounts and (in my opinion) will be willing to log in with social versus email/password. I think I'm looking more for a "pulse" of where things lie in terms of how the hypothetical average user feels now. Querying Hacker News is probably not the best place to ask (since most of us are engineers or of the technical ilk) but I'm trying to get as many opinions as possible. However like other people have commented, I need to directly engage the users (who don't exactly exist yet since I'm still building the MVP).
