Do I announce it to my "friends" or just disappear?

I'm Quitting Facebook and now time for the Big Question . . .

I only have 69 (heh!) friends and probably 50 of them are family. My Mom just emailed me to tell me she's deactivating her account and she's the only reason I've kept mine. I'll miss the family pics but I won't miss the echo chamber whenever I have posted something about an issue that was important to me. I've been talking about quitting for a while but now that the moment is upon me, I'm hesitating a little. Anyone else quit FB? Do you miss it?

ETA: I went with a post about it. 45 minutes later with no likes or comments, I deleted the fucker. Thanks for the advice kids!
