I recently searched “shtetl” on facebook to see what my friends had ever shared from the blog, literally only three posts:

• A 2014 post titled “eigenmorality” which I skimmed just now, appears to be a rationalist coded social credit system, this is probably not what students are looking for
• A post titled “NSA in P/poly: The Power of Precomputation”. This appears to have useful information about cryptography that I don’t have the expertise or energy to parse, also it’s from 2015.
• A 2016 post about the 8000th busy beaver number, bringing us full circle.

So in terms of the content worth sharing and alternatives, it appears it’s just the CS based stuff.

E: Joke answer: clearly the go-to contrablog is Scott’s nemesis Arthur Chu’s archived twitter feed, or just watching Jeopardy episodes.
