Aaron Bertrand lays out an argument:
I read fewer technical blog posts than I used to. This is partly because I find information differently, and partly because I’m 30 years into this. My reading habits say more about where I am in my career than about the value of blogging.
I write fewer technical blog posts than I used to, too. This is mostly a function of time and juggling work and life priorities, rather than a lack of ideas or perceived value in sharing them.
I still value blogs as places to learn, share ideas, and express opinions.
Given my entire schtick of finding and linking to interesting blog posts, I am naturally inclined to agree with Aaron’s points.
