I signed up for email updates for C++ Stories, so every couple of weeks or so I get informed of something interesting to read on the blog. The "Advanced Initialization Techniques in C++(20)" was the latest notification.
The darkening of C++ blogs might make some people think C++ is a has-been programming language.
I think there was a lot of excitement around C++11 and the years that followed that has since died down a bit. There was a lot of new things to talk about that really changed how C++ code was written. Now a lot of information just goes on repeat and the new features are more boring ones (but not unimportant).
Blogs, and forums like this one, seems to have been more popular in the past. This seems to be true overall, not just for C++ or programming specific topics.
Also, Bartek (cppstories) is a C++ Expert for the Polish National Body which works directly with ISO/IEC JTC 1/SC 22 (the C++ Standardisation Committee). So he knows what's going on re the C++ standard.
