Something is not right (in the API)

This is a test email for posting through a long string of APIs. About
six months ago, my connection between Posterous and Identica. This
morning, it was suggested that I attempt to authorized the connection
again.

It appears that the API for Posterous is a bit wonky because, when I
use "http://identi.ca/api" for the link, the authorization fails.
However, if I leave the link blank, it defaults to the same URL and
authorizes the connection.

WTF?
