Actually, you did just that. You grouped Finnish together with Scandinavian languages (a subgroup of North Germanic languages) whereas it has nothing to do with them. Also, Nordic languages don't include Finnish either - the languages spoken in Nordic countries do, but the group of Nordic languages (North Germanic languages) doesn't - however, the Convention of Nordic Languages does include Finnish, as they're referring to languages spoken in Nordic countries.
I'm just being really picky about this, but oh well, I was the one who started it. Sorry about that.
Just out of curiosity, what does Estonian sound like to you? I quite dislike how Finnish sounds, but really like Estonian - it just has a softer tone. Also, it appears to have quite many loan words from Germanic languages (because of a shared past) that have different words in Finnish.
