For my sins, I have a Facebook account - I am a Supporter of Wikipedia Review, among other things - and very recently the website is quite keen that me and JF become chums. As ever, when someone other than immediate family or people I know in real life, I drop into their page and see what it is that we have in common. Zilch, it would appear, is the answer between me and Jimmy F.
So, how come he pops up just as often as my cousins pals? Perhaps my Facebook WR involvement, and the fact he has Wikipedia noted in his hobbies/interests, is sufficient for Facebook to suggest me upping my 30-40 friends listing (I am not interested in being "friends" with anyone outside of my family, my RL friends, and other website acquaintances of long standing).
