filing taxes online is an unusually mixed emotion.
I'm both happy to be efficient, and creeped out by the implications. Both annoyed by my responsibility to the government, and happy to be using the internet, which seems like a freedom enhancing thing to me.
It's like talking to your oppressor over PGP or something, a mixing of metaphors and associations that isn't quite unpleasant, but not good either. coffee that's just been poured over ice cubes, and it's both hot and cold.

but, I also get a tax return soon :-)
