My guess is that the older folks who have the experience to speak deeply about these topics aren't interested in maintaining a blog. One of my most interesting college professors worked on chess engines professionally. He has a small online presence, but his commentary is usually in response to pointed questions or wild claims about chess engines.

The guy has stories upon stories about both hardware and software design and their impact on performance at both high and low level. All of his tangents in class were downright fascinating.
