In Case You Forgot, NVAlt is Awesome
Select some text on a web page and right click and create a new note in NVAlt.
The new note is added in the background and the URL is included as meta data.
Copy a URL and switch back to NVAlt. Hit shift-cmd-V to paste as a new note.
The source is downloaded into a new note and Markdown-ified.
So yeah, pretty crazy awesome application that they make for free.
