Erm, I see... I think it depends on the context used because it could be hurtful I guess. When I think something is "lame" I dont't say "that's so hetero." Anyway, they don't use that term here in Brazil (they say 'crap', 'sh1t', or stuff like that) so I'm ok.
I wouldn't be offended if someone said that's so hetero. I'd laugh. So yeah, I havn't commented on your tag yet, so... I like the blue one a little bit better. The first one just looks a little too plain.
2nd is hot, I think the txt goes well with the colouring and it feels like an underwater kinda tag. Way kool. And I told you in PM, but it totally doesn't look like Hilary haha, the brown hair put me off! Looks like Catherine Bell. Good job though bud, very appealing. To me anywoo! =D
