I wanted to post to a blog easily from “anywhere”. Well, anywhere means an Android phone or the command line. WordPress was the choice because it supports a XMLRPC mechanism to post and do other stuff.
I successfully tested posts from the phone with wpToGo, and from the command using the script from John Bokma:

it is great!
