I‘ve been a fan of Greg Linden for a loooong time. Heck, he even tipped me off to MapReduce back when it was just a moderately interesting distributed programming model and well before it was a hip ecosystem. Although now he‘s much more intermittent, I still enjoy his posts which are much more link dumps, such as this, these days.
I suspect he‘s adding more depth over at his G+ abode, but that‘s One Social Network Too Many © for me.
