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
12  * information.
13  * Posts that originate externally or do not fall into the above
14  * posting categories go through item_store() instead of this function.
