Trademark rights arise once the mark is used to identify goods in the stream of commerce.
Registration gets you two things:
1. The scope of your mark applies beyond your geographical area.
2. Registration on principal register is constructive notice to the nation. It creates nationwide coverage and removes defenses of good faith and lack of knowledge.
If "Programming Praxis" is not registered, then Daily WTF can asset good faith and lack of knowledge defenses. I don't think that the geographical limitation issue has much weight on the internet. Those would be the only differences.
Registration also puts a nice, convenient stake in the ground of who was there first. I don't think that will be an issue here.
