What is the QBSW (QuickBase Service Worker)?

> I am really curious to see what Service Workers are capable of.
I use them today in Chrome, and FireFox but I am waiting for Service Workers to land in Microsoft's Edge browser (they are in development now) before posting public examples:

https://developer.microsoft.com/en-us/microsoft-edge/platform/status/serviceworker/

You probably are using Service Workers from other sites already and didn't know it due to you casual browser history. Check for your installed Service Workers using these URLs:

Chrome
chrome://serviceworker-internals

FireFox
about:serviceworkers

Opera
browser://serviceworker-internals

Here is a handful of non-developer sites that have active Service Workers installed on my boxen:

Twitter.com, Weather.com, Pinterest.com, TheGuardian.copm, WashingtonPost.com, YouTube.com

If you find something interesting send it to me! Other than the occasional blog or presentation it can be difficult to find material on Service Workers. I actually visited a local university computer lab and harvested all the installed Service Workers the other users left behind on the computers. Now I am the president of the Service Worker Union!!!
