I don't agree at all. The author only considers short term productivity and does not acknowledge the long term benefits of the skill sharing.

Let's make up a metric, du (dev units), for how much a developer produces in a day, and let's say an average developer produces 100du per day.

If we have two developers, Sally and Frank, producing 120du and 70du respectively. Short term, for these two people to pair program, the production of the pair programming has to be greater than or equal to 190du.

But if we instead consider how productivity increase as experience grow, perhaps the next day, Frank will produce 80du and Sally 121du, then this is definitely worth it long term.

I would agree with the author if the question was "ONLY pair programming" vs "ONLY individual programming", but that is a stupid question.

Looks cool but I don't like the idea of pushing a library on the user when they would most likely not use that kind of navigation anyway. Ever wonder why your browser is using 16Gb of RAM? This is why.

If the user is already using the keyboard to navigate, it would be better for them to install an extension like Vimium (which I think is vastly superior because it affects the whole browser.)

With this navigation I would potentially have to do more than 10 key presses to reach what I am looking for and with Vimium I have to press at most 3 no matter where on the page I want to go.

Shouldn't every currency have a theoretical market cap relative to another currency?

If there are 1 billion Thai Baht and 1 baht trades for 1.0 USD, then the Baht should have a 1B USD market cap in theory.
