Compare with http://lesswrong.com/lw/f1/beware_trivial_inconveniences/

I was reminded of this recently by Eliezer's Less Wrong Progress Report. He mentioned how surprised he was that so many people were posting so much stuff on Less Wrong, when very few people had ever taken advantage of Overcoming Bias' policy of accepting contributions if you emailed them to a moderator and the moderator approved. Apparently all us folk brimming with ideas for posts didn't want to deal with the aggravation.

Okay, in my case at least it was a bit more than that. There's a sense of going out on a limb and drawing attention to yourself, of arrogantly claiming some sort of equivalence to Robin Hanson and Eliezer Yudkowsky. But it's still interesting that this potential embarrassment and awkwardness was enough to keep the several dozen people who have blogged on here so far from sending that "I have something I'd like to post..." email.

In the end the effort to post in Main is exactly the same inconvenience addressed in that post.

Except that here where it is possible to post in Discussions it may be actually a sensible distinction.
