It isn't mentioned in the blog as far as I can see but the author appears to be advocating "micro habits" (also known under similar and other monikers, small habits, BJ Fogg's method etc).
The idea being you pick up a new habit using similar techniques to pomodoro, a little bit at a time.

One thing I did find useful in this particular essay (the OP) was a reminder of the relative difficulty of spending X amount of time doing something new compared to the same amount of time doing something second nature - which is magnified further according to how boring, painful, or just plain irritating it is.
