I tend to agree with Yvain, one has to write specifically for the LW audience in order for a post to be well received. I don't have my own blog, but I do have half a dozen post drafts on this forum which will likely never see the light of day because they are not in a shape acceptable for posting here.
Most of Yvain's stuff would go straight into Discussion with no problems. Post them here?
Ever since Eliezer, Yvain, and myself stopped posting regularly, LW's front page has mostly been populated by meta posts. (The Discussion section is still abuzz with interesting content, though, including original research.)
Luckily, many LWers are posting potentially front-page-worthy content to their own blogs.
Below are some recent-ish highlights outside Less Wrong, for your reading enjoyment. I've added an * to my personal favorites.
