I am a registered user, and overall really like the concept and much of the execution. Sadly, I find the search function to be almost useless.

Search does not do partial text searches, so for example:

if I have two recipes, one of which calls for "buffalo stew meat" and another of which calls for "buffalo or bison," searching for "buffalo" yields no results.

Thus, you must know the /exact/ name of any ingredient you want to search for, and since there is no component to normalize ingredient names, I can't effecively search through my own (or online) recipes. In an email, the developer did indicate that he would look into this for a future version, but in the meantime, sadly, I'll have to resort to another tool.
