Geez...I post a bit of informative information that should affect virtually everyone (to varying degrees) and it turns into a debate.
Yes, you can pay most of your bills online and use email. But to the defense of a lot of people, we can't pay every single one of our bills online, we can't send Christmas cards online (yes I now there are greeting emails to send but it's not as personal), etc. So, even if you avoid snail mail as much as possible it's still a nuisance as before you get through that one book of $0.50 stamps for that mail that you need to send snail mail, you need a book of $0.01 stamps due to the price increase and so on for every increase (you never catch up). OK, you'll say don't buy a full book of stamps. Well, going to the post office is a nuisance (hence, why people pay online and use email), so 1 trip is better then mutliple trips and the book is more convenient.
That's all.
