[Edit: My points still stand, but this isn't an issue worth fighting over. I've gone back and edited my post.]
Look for the bar at the right side of the page. Look down to the part where it says "Recent on Rationality Blogs". The current top link there is the same link as what I gave. I therefore disbelieve that he asked that he asked not to link to it from Less Wrong, or that he still supports such a request if he did make it, because Less Wrong itself links to it in the sidebar! If it is true that we shouldn't link to his new blog, shouldn't the site itself be abiding by that as well? I trust the administrators of Less Wrong to not go against Yvain on that.
Speaking of the sidebar, is there any way to make it optional whether a post goes up there? Maybe by including [LW] in the title or something? I enjoy blogging about rationality, but I also enjoy blogging about random things that go on in my personal life, and it's kind of embarrassing to have those show up on the LW sidebar.
If it's worth saying, but not worth its own post (even in Discussion), then it goes here.
