I know a few full-time infosec professors who spend a ton of time on twitter. You would expect these people to lead path-breaking research in their fields, but all they do is share memes about infosec, and ofcourse a few papers a year written mainly by their grad students. But maybe they too are salesmen types. Marketing their services to midwit management people on twitter. I include politicians in this too. Hurr durr china is going to defeat us in "cyber space" opens up a lot of business opportunities for government contractors. No one care about compilers, or operating systems the same way.
