Just a quick heads-up that yours truly has a blog on Medium now, too.
As I write in the first post, my only reason for signing up is out of sheer geeky curiosity. I don't like writing in a browser and not being able to write in Markdown, but for what it is, Medium is very well done. I don't know how often I'll be updating, but I've enjoyed playing with it. An iOS app would be nice as well.
So, check out what I've written so far. In the future, I'll link here to new posts over there.
