Could not agree more! Even if this is not easy to achieve you always need to repeat that KISS motto in your head while looking through the viewfinder. I believe so much in this principle that this great quote from Charles Mingus is the first sentence of my artist statement [1]: "Making the simple complicated is commonplace; making the complicated simple, awesomely simple, that’s creativity".
And the photographer author of that article nailed it when she wrote: "Minimalist photography attempts to explore how much information can be taken away from a composition, before it loses its impact".
I also like this quote from Antoine de Saint Exupéry:
"Il semble que la perfection soit atteinte non quand il n'y a plus rien à ajouter, mais quand il n'y a plus rien à retrancher",
which can be translated as:
"Perfection is finally attained not when there is no longer anything to add, but when there is no longer anything to take away".
The difference seems that The Thread Group is solely focusing on the network protocol [3] and not a full IoT platform like AllSeen and OIC.
And apparently, Nest thermostats are already running a version (is it the final one?) of the Thread protocol.
