"Joe, other notetaking and productivity tools lock you into one rigid way of organizing your notes, tasks and contacts. And to get the most out of them, they charge you a subscription fee, and your information is ‘out there’ online waiting to be hacked.
TiddlyWiki is different. You store it locally (or online if you wish). It is 100% free. And it is infinitely customizable to match your style. Links, lists, tags, fields, templates, transclusions, widgets, plugins, stylesheets and macros give you many ways in which to organize and display your content. You don’t need to learn all of those things at once. TiddlyWiki is something you can continue to grow into.
Also, you can download as many TWs as you like. I have one for my to do lists, one for my contacts, one for my important on hand information, and one for my reading notes. And as a teacher I organize TiddlyWiki files to give content to my students. And I have other files I use to generate public wikis made up of statc html pages, for publishing on the web.
If you need a collaboration tool, need to import images, or need to do handwriting on your text notes, TiddlyWiki is probably not the tool for you. But if you need to save textual information quickly and organize it in multiple ways that match your way of doing things, TiddlyWiki is the tool for you.
Also, if you don’t give TiddlyWiki a try, Joe, you are no longer my friend."
