Há algum tempo, me deparei com um interessante software chamado MailNoter (escrito por um dos autores principais de TortoiseSVN).
O objetivo principal é enviar facilmente conteúdo (web) para sua caixa de correio, para que você possa ler mais tarde.
O site apresenta a melhor ferramenta:
MailNoter is a small tool to help gathering notes from various applications, but specifically from browsers.
There are many tools and applications out there which help to keep a repository of personal notes, and even though some of them are very good at what they do, they all either use a proprietary format to store the notes (what would happen to my notes if the app isn't supported anymore and stops working on future OS versions?), only store notes as plain text, require non WYSIWYG input (e.g., Wikis), don't allow attachments, don't work if there's no network access, or are just plain ugly.
So I'm keeping my notes in my email account:
- open storage format
- available from different computers and OS
- works offline
- usable with any email client
- usable through a webbrowser (no need to install anything if I'm at a place where I can't just install apps)
- easily searchable (either through the web interface (did I mention I'm using GMail?)), through desktop search engines or the email client itself
And with GMail, I can add tags to my notes very easily, which makes searching them even easier.
