Yeah, Michael -- only, too bad they sometimes get cleared.
At first I thought that only happened when profiles were slow to come up and I hit OK before waiting for it to load, after visiting the notes page. But I find that's not the case, or at least not the only case. Oddly, it seems to happen more often with some peoples' pages than others -- I have a friend where I know it got erased 3 times over 8 months, and others I've known for a year with no problems.
Regardless of this quirk, notes are definitely a good thing to use.
