I've been doing all my personal notes etc that I want a rich text format in .ODT for decades now and don't regret it one bit.

I do regret being overly paranoid in my 20s and not writing down my master passphrase to my personal documents -- I lost a huge chunk of diaries and writings due to that.

Fun fact: ODT uses Blowfish encryptio. Remember when we made Bruce Schnierer a meme like Chuck Norris? He wrote it -- apparently it's faster than AES?

Anyways, if you save with password in a .ODT file, if you pick a strong password you've got a nice little self contained encrypted volume that doesn't require "suspicious" software to open.

ANYWAYS, a bit of a tangent but... looking forward to death of Word.
