I just encountered two FF extensions (Scribefire and Deepest Sender) that store your username and password for your blog. When you find some text on a page you want to blog about, highlight and hit a toolbar button. Up pops a WYSIWIG editor with your content in it. Add a title, tag it, and post to your blog. Awesome.
From the Wordpress site,
"WordPress uses an XML-RPC interface. We currently support the Blogger API, metaWeblog API, and the Movable Type API."
This would really streamline blogging. Wordpress can't accomplish everything I need without serious hacking. Has anyone done or plan on doing anything like this? If not, how messy would it be to integrate a wordpress blog into a silverstripe site?
