* This is the POST destination for most all locally posted
* text stuff. This function handles status, wall-to-wall status,
* local comments, and remote coments that are posted on this site
2011-02-04 22:37:04 +01:00
* (as opposed to being delivered in a feed).
* Also processed here are posts and comments coming through the
* statusnet/twitter API.
*
* All of these become an "item" which is our basic unit of
2011-02-04 22:37:04 +01:00
* information.
