Here's how to kill two birds with one (gamified) stone : If you host your static blog on GitHub Pages, you'll get a 'contribution' point for every day you post (or even commit) to it. Thus building up your GitHub streak, and post count/size consistently.
This only works if you value your github streak number/commit stats. "measure your self-worth by" implies that all other values are secondary, which would just be silly.
