It looks like there is a Security blog with great articles, but it has a banner at the top that says it is an archive. When you click on the banner, however, the About page it leads to has nothing to that effect and looks like the site is still up. But there is also a box in the upper right that links to http://blogoverflow.com, which redirects to an error page.
So what is the deal with Schrodinger's blog here? Is it alive or not?
the About page it leads to has nothing to that effect and looks like the site is still up.
Because it's an archival copy of the About page that existed when the blog was active. The banner on top is present on the About page, and indicates its archival status.
Indeed, the existing links to http://blogoverflow.com/ redirect to https://stackexchange.com/blogs which shows Page Not Found. A more specific error page may have been better, but the behavior is valid, as the site no longer exists.
There were plans for a new blog, completely separate from the previous instance. See
The upshot is: there was some vague interest, but nobody put in the time and energy required to make it happen.
