One thing I'd love to see if you embark and stick to this new year's resolution is creating a blog post per man page with all the exercises and examples you tried out by applying what you've learned from each man page. It'd be great if each post included something like:
(1) What is the command
(2) What kinds of things you can accomplish with it
(i.e. why should I learn this command? how will
it benefit me)
(3) Examples of the command applied by itself
(4) Examples of the command applied in conjunction with
commands you've previously written about via piping.
