[bloggerDev] Valid token, but can't post to blogger

I'm having some problems trying to post to blogger using AuthSub
authorization.

I do an AuthSubRequest, get a one-time token back, send it to
AuthSubSessionToken, and get back a session token. I can pass this
session token to AuthSubTokenInfo to see if it's valid or not and get
this response:

Target=localhost
Secure=false
Scope=http://www.blogger.com/feeds/

Which means it's valid, right?

But then when I try to post thru the blogger api:
http://www.blogger.com/feeds/MY_ID/posts/default

I end up getting a 401: Token invalid - Invalid AuthSub token.

I thought I followed the docs on how to do this, but am I missing
something?
