Why not? Is it that hard to believe that 6 million of the people that joined Google Plus early on are software engineers? According to the BLS there are 3.2 million Americans in "Computer and mathematical occupations" (http://www.bls.gov/news.release/ocwage.htm http://www.bls.gov/news.release/ocwage.htm), and there seems to be a reasonable consensus that 12 million is an upper bound for the world (http://stackoverflow.com/questions/453880/how-many-developers-are-there-in-the-world http://stackoverflow.com/questions/453880/how-many-developer...). There's no way 6 million are on Google+ already.
