A lot has changed over the years. I now do a lot more than just rails and having railstips as my domain seems to mentally put me in a corner.
As such, I have revived johnnunemaker.com. While I may still post a rails topic here once in a while, I’ll be posting a lot more varied topics over there.
In fact, I just published my first post of any length, titled Analytics at GitHub. Head on over and give it a read.
