A few ways.
If you like to keep things old fashioned, you can receive an email when new posts are created. This can be done by selecting the “+Follow” option in the lower right corner of the page.
If you use Twitter, you can follow @durhamdotio. I personally find Twitter rather deficient for this task, but its UI provides minimal friction to “follow” things, and WordPress has Twitter integration which tweets every post I make automatically.
You may also sign up for a wordpress.com account and follow this blog there. I would however recommend RSS over this solution, unless you’ve already got (and use) an account.
