For me, I do it rather blatantly.
That's because where I live, people say: "Oh, me too! How many have you watched?" Great start.
...
And then I discover they only watch a few. Mostly Naruto, Bleach, or Gundam. Mention anything more, and then I get something like "Lucky...Lucky What?"
Eh, they don't even know Rozen Maiden.
Oh well, otakuness could improve down south here. At least everyone knows Haruhi.
