There's a plugin for Xfce4 called Notes that I use. It's hands-down the best such program I've used, so much so that it's a real barrier to switching away from Xfce. In the past, I've used text files on the desktop and e-mail drafts. This program (text only, no formatting/embeds/hyperlinks, does have named notes) sits on my top menu bar, and in one click opens up to fill half my screen. If I've used it today, it'll open up where I was last. Another click and it's gone, automatically saved. I don't know exactly how much I get out of it, but I definitely recommend some form of note-taking for everyone browsing the Internet.
