Regular note-taking is one of the most productive habits a person can practice. The ability to take notes online and access them anytime, from any location is priceless. Over the last few years, I have personally tested nearly 100 different ways to do this. Some of these note-taking systems are worth mentioning, and some are worth forgetting.

Here are the systems worth mentioning… a list of 40 useful online note-taking techniques and web applications, categorized and listed in no particular order:

Casual Online Note-Taking

When your note-taking requirements call for speed and simplicity…

Gmail Yourself a Note – I used to do this several times a day. If you have a smartphone with email access, this is one of the quickest and most basic ways to create an online note on the fly. I setup a special “to-do list” Gmail label (folder) for storing and processing all of my notes.

Delicious-Tag a Note – Quite frequently we find articles online that remind us to do something, or inspire us to try something. Tagging these articles with a “personal note” tag and entering an insightful comment in each bookmark’s “notes” area turns Delicious into a productive note-taking (and collaboration) tool.

So imagine creating a note-taking or to-do list document that was synchronized across all of your computes (work, home, etc.) Every time you modify the note on one computer, the changes are instantly accessible elsewhere on your other computers.

UberNote – A little more sophisticated then the average casual note-taking web application, but not quite as feature-rich as some of the other full featured online notebooks. A key feature is its ability to store to-do list tasks in various notes and then view all the open to-do list tasks in the “Open Tasks” list on the sidebar. I also like the way UberNote allows you to create notes via email, Firefox bookmarklets, AIM, and the iPhone.

Its key features include multi-user collaboration, quick clipping of web pages using the Google Toolbar, public sharing and publishing of notes, and integration with Google Bookmarks and Google Docs. One big problem though… Google recently announced that it is no longer supporting new development for this service. Google Notebook will continue to exist, but there will be no new software updates and, even worse, the browser extension will eventually be discontinued.

Odds and Ends

A few additional ways to take notes online…
