If you’re going to organize your recipes any one way, I’d like to recommend onetsp. They are a very affordable, on-line recipe manager that hits all the geek buttons (markdown, web clipper, extra notes, export, et. al.).
I’ve been a happy customer for a few years and the only complaint I have is the inability to alter tags in bulk. You can share recipes via email. Overall, if you’re looking to digitize your recipes, this is the tool I’d recommend.
