There have been several posts in recent weeks on this topic, and every time I have the same reaction: how can they all just ignore TiddlyWiki [0], that has been out there since 2004 and has evolved nicely over the years to deliver most of the same outcomes? Is it that folks just ignore prior art? or they just gravitate to the latest more sexy software? (honest question).
I've been using TiddlyWiki on and off for many years, but 2-3 years ago I moved heavily into it (the Drift [1] distribution), and I haven't looked back. To me, it has become less about the tool and more about the information, and ensuring I have complete access to it, even 20 years from now. That includes data, metadata and even the software itself, regardless of the platform or OS.
