Those are probably skills you want to get better at anyway, right? Even if "your code speaks for itself", I. Your career you're going to need to write (or at least contribute to) documentation, specs, requirements, proposals, pitches, business plans, here's a _lot_ of writing tasks that are really just "part of the job", hell - you're going to have to write a few versions of your cv and matching cover letters.

Maybe "actually doing work" by blogging is more of a skillset increasing (and caree advancing) exercise than it seems at first...
