Quote from DefragWhile Thrik is 100% right about popularity of blogs being strongly related to community participation and 'celebrity' factory, you should bear in mind that blogging isn't all about popularity! For me, blogging has been a very effective tool for rationalising and better understanding the subject matter of each post. In particular, it's often the case that we just 'know' why something works or does not work. When you write a blog post about the topic, you must understand the topic before you can explain it to someone else. On quite a few occasions, I've had "aha!" moments while typing a post
. My job up til now has involved convincing software engineers to change the way they write their code, so being able to put forward a convincing argument was extremely important to me, and blogging definitely made a difference.
I would thoroughly recommend blogging as a way to better understand your chosen field.
out of curiousity, which code changes are we speaking here? anything you could disclose?
