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.
If it's worth saying, but not worth its own post (even in Discussion), then it goes here.
Notes for future OT posters:
1. Please add the 'open_thread' tag.
2. Check if there is an active Open Thread before posting a new one. (Immediately before; refresh the list-of-threads page before posting.)
3. Open Threads should be posted in Discussion, and not Main.
4. Open Threads should start on Monday, and end on Sunday.
