There are a few mainly .net in my case: @fekberg, @pragdave, @ericlippert, @ahejlsberg, @slluis, @martinfowler, @unclebobmartin, @davidfowl, @DamianEdwards, @shanselman, @Nick_Craver, @spolsky, @kevinmontrose, @codinghorror, @marcgravell, @filip_woj, @frystyk, @dhh, @tjanczuk, @troyhunt and most importantly: @jonskeet

There are other issues that people care about in the world besides technology. Some of these things may matter more to the people you reference than technology. Dismissing care and consideration for the world around someone as "rants about social justice" does them a disservice. Also, one of the joys of Twitter is that you can always unfollow someone if they get to be too noisy.

p.s. I recommend you do not follow me on Twitter. Although I do, on occasion, tweet about iOS development, more of my tweets are about photography (mine and others'), and social justice.
