I'm honestly surprised you've met people in real life named Linnea; I expected to find that you were Swedish on your profile, but it says North America. Are you in an area with a high Scandinavian population?
As for the name itself, I think it's beautiful. My preferred pronunciation is li-NAY-ah, but sometimes I'm afraid it'll be read as LIN-ee-ə without the accent (Linnéa). Linnaea, meanwhile, just looks weird to me, even if the pronunciation is no longer ambiguous.
