I think so. If it wasn't so instrumentally useful due to its continuing readership, I'd just freeze the whole site and let it sit there as an archive and never have to delete spam comments again.
So you think you can reach a wider audience because many of those people will (for whatever reason) not follow you here.
I think another reason could be: Because one day I want to write a book.
Eliezer once told me:
If there's one rationality skill I like to think I'm pretty good at, it's this one: the skill of saying "Oops."
In fact, I say "Oops, fixed, thanks" so often on Less Wrong I once suggested I should have a shortcut for it: "OFT."
And I don't just say "oops" for typos and mistakes in tone, but also for mistakes in my facts and arguments.
It's not that I say "oops" every time I'm challenged at length, either. I don't say "oops" until I actually think I was significantly wrong; otherwise, I stand my ground and ask for better counter-arguments.
But I'm sure I can improve.
Wanna help me debug my own mind?
Tell me: On which issues do you think I most obviously still need to say "Oops"?
