Abo-abo over at (or emacs has been blogging up a storm. So much so that it's hard to keep up. In a couple of recent posts, he describes how he interfaces his browser to Org mode. The idea is that he can click on a link in the browser and get a link stored in the appropriate Org file and tree.
I've been meaning to figure out
org-protocol and see if I can use it to advance my work flow so abo-abo's post is really timely. It serves as a go-by for using the protocol. He also has a pointer to the part of his Emacs configuration that uses the machinery he describes.
Really interesting stuff. You should definitely take a look.
