If Yvain was posting all his SSC stuff to Discussion/Main, wouldn't there be even more frequently a new post in Main than there is on SSC?
Sure, but LessWrong is a forum for a set of very specific topics, specifically instrumental and epistemic rationality, not just a place for whoever is on LessWrong to post about whatever they want to.
Many of us have our personal blogs and they fill a different niche than LessWrong does.
This thread is for asking any questions that might seem obvious, tangential, silly or what-have-you. Don't be shy, everyone has holes in their knowledge, though the fewer and the smaller we can make them, the better.
Please be respectful of other people's admitting ignorance and don't mock them for it, as they're doing a noble thing.
To any future monthly posters of SQ threads, please remember to add the "stupid_questions" tag.
