Have you had the unfortunate necessity to use the IRS web site? It's actually fantastic. Getting logged in and authenticated is pretty weird, because you have to put in a credit card number or a loan number, but it's pretty good authentication for the audience.

The web site itself is snappy, well written, and I could do everything using Firefox on Linux. No "IE only" bullshit. Downloads are fast.

I'd give the IRS 10/10, except for the fact that I owe them money.

I had to use the social security website the other day and it wouldn't let me log in after working hours. Told me to try again at 9AM the next day. It's a joke.
