The site describes itself as "a fanpage created by shareholders, for shareholders."
Sounds like my cup of tea, and I love the choice of domain name. (at the time I am writing this, BRK-A.com is not yet taken...go for it!)

At first blush it seems to be a large collection of largely boosterish articles about Berkshire and its subsidiaries.
There are quite a few articles, divided into sections for Headquarters, Subsidiaries, and Investments, a useful and sensible division.
It appears to be around an article a day since March.

Having read a bit more, I begin to suspect a lot of (all of?) the content may have been written by ChatGPT.
All of the illustrations seem to be AI generated, too, and not by one of the better AI systems.
Not that this conclusion is necessarily bad, but it's hard to spot much in the way of insights, so the time spent reading doesn't seem to be particularly well spent.

Other comments?
