Hi. I’m John Proffitt. Gravity Medium was my active blog between 2008 and 2014.

  • 2008 – 2010 : I started Gravity Medium in early 2008 to write about public media and its struggle with a transition to digital products and services.
  • 2010 – 2012 : I left the public media world and largely stopped writing about it. Gravity Medium was pretty quiet as I re-entered the nonprofit and healthcare technology field.
  • 2013 : I turned the focus to healthcare IT, especially for nonprofit Community Health Centers, but never found enough time to keep it up or build and audience, especially since the move from Alaska to Ohio shook up my schedule.
  • 2014 : I changed gears once again, but still posted about technology and a few other areas.


  • Information Technology (IT) topics, with an eye toward stuff that may be useful to nonprofit organizations or small/medium business. After living and working in Alaska for 12 years, I’ve developed special knowledge on how to create reliable and sustainable IT for smaller firms.
  • Strategic perspectives on business culture, leadership, and community value.
  • The application of IT to advance nonprofit missions.
  • Consumerization of business technology, the Bring Your Own Device (BYOD) trend, and the future of what we call “corporate IT” today.
  • Digital media, journalism, the media business, and the intersection of media and public knowledge

Technologies of Interest (2014)

  • Chromebooks and Chrome OS
  • Web-based collaboration platforms (but not SharePoint, please)
  • Google Apps features, business usage, and operations (in fact, I’m a Google Apps Certified Deployment Specialist)
  • Microsoft desktop and server technologies (that actually work well)
  • Network design and operations, including LAN and WAN technologies
  • Anything made by Meraki or Apple
  • Google’s Nexus line of devices
  • Healthcare IT
  • Network security, data security, encryption
  • Quantified Self technologies — fitness trackers, personal biometrics, personal genomes

My Commitment

Unlike most paid journalists, I’m just this guy sharing what he’s found, what he’s learned, and what he thinks. So I’ll do my best to tell you:

  • what I know from experience
  • what I think I know
  • what I don’t know
  • what I suspect
  • and I’ll ask you to correct me when I’m wrong

Links and Attribution

I try hard to link to sources and provide attribution. If I ever miss a link or fail to provide credit where it’s due, please let me know.


I have 3 rules for comments:

  1. This is my site. (And conversely, you can have your own site — it’s free.)
  2. I encourage respectful and engaging comments.
  3. I decide what’s “respectful” and “engaging” when it comes to comments here, and I can/will dump comments that don’t meet the test.
