Is blogging dying? I don't think so. But it's gotten a lot more serious over the last few years. Casual communication is now done through social media. Blogs aren't trendy right now because all those current Facebookers and Yik Yakers discovered blogs around 2007, and then abandoned them en masse around 2010.
But the old school bloggers are still around. They were blogging first, and they're still blogging. Blogs have just become the home for serious, long-reads.
In the early oughties, bloggers divided themselves into linkers and thinkers. The linkers have moved on to other formats. The thinkers are still blogging.
The biggest blog in economics is Marginal Revolution. It's been written by Tyler Cowen and Alex Tabarrok since 2003. Their blog was a category killer from like Day One. It remains one of the most popular of all blogs.
In 2004, before blogging became the new thing, Tyler opined that he'd like to teach a whole class some day, where the students did nothing but blog their own ideas, and comment on the ideas of other students.
I took that to heart, and started this blog in Summer 2004 with a principles of micro class. This is the first, and the oldest blog, for which students wrote for a significant portion of their grade.
Keep up the good work.
