I appreciate your effort to build up our community.
For Windows users, I found out EVERNOTE can do subtags, and it has other nice stuff like posting directly to facebook, attach files, saving screenshots (with a browser pluggin called Evernote Web Clipper), creating checklists, and more.
I will start applying what I just learned from this awesome post, and of course, clip it to Evernote. Thank you very much for the ninja lessons.
