Metafandom
If anyone ever wants to link to anything in my LJ from Metafandom, please ask me first. Most of the time, I suspect I'd probably not mind, but there might well be times when I did.
I post public so that friends I didn't yet know were on LJ can drop by. That's not quite the same as being read by a horde of strangers. (Even though I don't friend everyone who reads this journal, most of the people I haven't friended per se are still people I know and whom I am happy to have reading stuff.)

I will try to remember to do as you ask but I may forget if you write something really interesting that I want to tell the world about.

Metafandom is too big. I've no desire to risk flame wars because someone further afield who doesn't know me or read my journal regularly suddenly takes issue with something I say after having it linked.
Look at it this way - I post public, but I picked the option that keeps search engines out.
I've seen two friends linked recently and while one was okay (even though she would have prefered the courtesy of being asked), I feel that the other one would rather not have.

I only friends-lock stuff if it is work related and likely to get me in trouble or self-indulgent moaning that people that don't count me as a friend don't need to know - however I think it is common courtesy that before you repost anybody else's stuff you should ask first - after all they are perfectly capable of reposting it themselves if they wanted too.
From the communications I have had with others I think most people accept this as reasonable behaviour - but there is always the odd occasion as you say.
