I remember seeing a study investigating the proportion of active accounts, vs. the number of dormant accounts. I think the study found that only about 20% of accounts were active. I can only imagine that the ratio of real accounts to automated accounts is far worse.

I also think that SV peeps use twitter at a far higher percentage than the real world, leading to very skewed perceptions.

Really? I know a lot of people around the world who use Twitter, ranging from notable authors to famous physicists to fashion designers to hockey sportswriters. G+ MIGHT get there but for now, I know far more variety of disciplines who actively use Twitter over G+ and Facebook.
