5 * This is the POST destination for most all locally posted
6 * text stuff. This function handles status, wall-to-wall status,
7 * local comments, and remote coments that are posted on this site
8 * (as opposed to being delivered in a feed).
9 * Also processed here are posts and comments coming through the
10 * statusnet/twitter API.
11 * All of these become an "item" which is our basic unit of
13 * Posts that originate externally or do not fall into the above
14 * posting categories go through item_store() instead of this function.
