Thanks! It would probably be more helpful to categorize these blogs by topics. I can see some Russian/Hindi blogs, would be nicer to have them listed separately.

    Actually, I had these blogs starred, so I didn't do much work here as I just ran a script on my favorite blogs page and then copy-pasted to create this blog (you can see that each blog title is ending with \n). But I will categorize them when I find time.

Great as it is, those compilations wouldn't be needed if there was working search by tags

Matriod intersection barely has any applications in geometry algorithms. It's name might seem to be wierd and delusive, but this topic originates from linear algebra.

Details

I think that it is better to move matroid intersection tutorial from geometry to general mathematical stuff (or probably graphs).

I cant believe you didnt include my anime blogs. When compiling a list of most useful codeforces blogs ever, one doesn't simply just leave the anime blogs out. >:(

    all jokes aside make a section for most interesting/funny blogs for comic relief since most coders don't laugh that much

Could you add "Problemsetting" section? Including blogs from this, and this...

Also I request to add Top 10 optimizations 2017- (collectors edition) to the Have Some Fun list! Although it covers all the educational blogs you already added.

If you sort article based on what is to be read first, it would become like a roadmap or something. Although, very helpful.
