This looks like a really well-written blog, but the way it has [tweet] links scattered around everywhere REALLY puts me off. It comes off as extremely arrogant. I hope Rob reads this...
The intent of the Tweet links is to remove the barrier to entry for people who want to quote pieces of the article. I've found that removing even a few seconds of work increases the chance that someone will think "hey, that's a cool quote to tweet."
I removed the links but given that it was an experiment I'm curious to hear what others think. Two people is a small fraction of the 5k or 6k who will read this post in the next 24 hours.
Great book by the way.
