I got sick of Evernote's feature creep, and decided to give "Notes.app" a try. This was partially because you can have some folders backed by Exchange, others backed by iCloud, and others backed by IMAP, so you have better control over your data.
To use this AppleScript, change the first two lines. Create the target folder in Notes.app before you run the script. (I put my work notes into my employer's Exchange server and my personal notes into iCloud for now.)
I could not find a way to set the creation date programmatically, and that's why I put it as the first line of each new note, so the information would not be lost. (I may update the script to do something similar with tags.)
