This is a fantastic first choice, particularly as it sets you up for using a more "real" database for sharing data/scaling in the future.
OTOH, you have to know when no to use it and step up (down?) to something that is text editor hack-able (XML!?) or has barn burner I/O abilities (yah actually just dumping raw buffers with regularized binary data to disk). Or for that matter is used to exchange data with other apps with other services (JSON, and the long list of other data dependent formats, although for at rest exchange I have to point at XML again).
