Writing a good article is a lot of work. When you write it for LW, you risk that (a) at the end your hard work will get downvoted, or (b) the thread will be off-topic or otherwise bad and you will have no control over it.
A solution is to post your articles somewhere else, and only submit a link with a short summary on LW. The disadvantage of this solution is that the debate is now split in two places: your blog and LW.
