Today, this site shows 24 thousand users in Cryptography. It runs in parallel with and is associated with StackOverflow boasting 6 million users. This site then clearly creates some leverage and impact for the cryptographic community, with the power to influence and shape minds. It can then somewhat shape the nature of cryptography in general.
I suspect that most users have not met each other, and probably use ids unique to this site so cannot be otherwise tracked in the wider Interweb. I realise that some people do post under their real names. There is also no vetting or background checking of new users. Anyone can join with a made up id and fake email address. They can then shape discussions and steer advice towards certain individualistic goals.
Even with my limited cryptographic knowledge, I perceive certain forces trying push agendas. It seems to me that there is a subtle movement towards certain approved cryptographic primitives and protocols. Rather than encouraging cryptographic diversity, there seems to be a drive towards a mono culture with all the adherent risks. Potatoes turned out poorly for the Irish. I suggest that AES be a similar contemporary potato for example. I can't tell, but as another example, there might be similar steerage with elliptic cryptography.
Since this is an issue of security, privacy and data protection, what is the probability that this site falls within the scope of the NSA Bullrun program? Are there any steps that Stack Exchange can take to mitigate the possible risk posed by intelligence agents / contractors steering this community? Hundreds of millions of dollars buys many internet café postings and online identities. There's some appropriate quotation about more things in Heaven and Earth...
I ask this specifically here as this is the only Stack Exchange site that a government would care about. It is a perfect target for counter intelligence programs. I also see this question as too important for Meta as it strikes directly at the heart of everything posted here.
