Is there a point to being in your own Friends list?
In particular, you can check the appearance of your posts in Friends view (and go back and edit them if you're as much of a perfectionist as I am).
For people who post protected entries, their non-appearance would alert them to being logged out.
I can't remember if you appear as one of your friendsfriends unless you Friend yourself.
I just look at my Most Recent Entries view, narcissist that I am.
Btw, friendsfriends is scary; it's disturbing to see all the goths and furries and sullen teenagers and random emotionally disturbed people in one's second degree. Though in looking at it, I've found at least one person I vaguely knew online years ago.

also handy to see your name in bold on someone's userinfo page. can't remember why this was of note, but i think i liked it because it was consistent. bold = someone in common. non-bold = people i might know or simply don't know.
