I have a Wikipedia blog. Been doing it for over a decade. I post articles I find interesting, categorize and tag them, do some light copyediting, find/create a 300x300 pixel image to illustrate each, format them in a digestible feed, and added a random button.
For years people asked me why I bothered. I did it because I love Wikipedia and wanted a record of my wikiwalks, but it has also become a fun example of my style and interests to show prospective clients.
