For the most part, the people you're looking for aren't here, they're on Twitter or Slack. The chatops and devopschat slacks are decent. On Twitter there are tons of great people to follow. My short list is @littleidea, @purpleidea, @yesthattom, @allspaw, @botchagalupe, @damonedwards, @bejammingh, @miah_, @netik, @realgenekim, @jezhumble, @bryanl, @antonbabenko, @brikis98, @sigje, @philiph, @phredmoyer, @mipsytipsy, @lizthegrey, @KrisBuytaert, @nathenharvey, @srhtcn, @gethash, @bridgetkromhout, @patrickdebois, @hashicorp, @pulumi, @ lkanies, @adamhjk, @ripienaar, @garethr

Hope this helps a bit.
