Diaspora needs more than privacy to become popular. Right now, I'm on the edge of simply quitting, and am mostly here just for #caturday
. I used to be an active user on a language learning site that allowed members to search for friends (which they called something like "learning partners") and many users used that to start real friendships. Today, most of my best friends are people I met that way. The site didn't care about their "social networking" features at all. The implementation was rudimentary and they never developed it further. Later, they were bought by another business, and the social networking features were removed entirely. But it showed me how easy it is to create real social networking online. Facebook still hasn't done that, and neither has Diaspora.
