There are many blogs on Codeforces, and most of them aren't very important a long time after publishing, like round announcements, saying "hello", asking for a better explanation of problem B than the one in the editorial, and so on. Among them, there are a few very interesting blogs that are a great resource of knowledge, like ODE by MiFaFaOvO, HLD by Vladyslav, suffix automaton by quasisphere or even Blogewooshes.
In my opinion, it would be great if there would be a special place for such blogs, accessible for example, by navigation bar, where they would be somehow sorted. It would be much easier to think "Let's learn something new!" and to do it. Also, probably Codeforces would have the greatest such base for competitive programmers. What do you think guys and MikeMirzayanov?
