I started this recipe blog so I can ditch my paper system of recipe cards in a box, but I've found it essentially just as difficult to let go of my cards as it is to get rid of cookbooks (gasp! the horror of the mere idea!). So I haven't really been diligent about using it, but I think it could work very well for someone who can more easily make the permanent leap to the computer for their recipes. There are tons of other recipe organizing ideas at
Monthly Round-up on OrgJunkie, check it out and then get organized yourself!
