There have been a bunch of posts on self-help related topics (akrasia, social skills, etc.), and some of them have been very well received, so if that's the topic that you're referring to then it could fit in fine. Yvain was just giving his own views, not setting official LW policy (and he's clarified his views with another comment here).

If you want feedback on whether people would be interested in your post, you could give a two sentence summary of it, either here or in the open thread.
