Things and Stuff Wiki - An organically evolving personal wiki knowledge base with an on-the-fly taxonomy containing a patchwork of topic outlines, descriptions, notes and breadcrumbs, with links to sites, systems, software, manuals, organisations, people, articles, guides, slides, papers, books, comments, videos, screencasts, webcasts, scratchpads and more. Quality varies drastically. Use the Table of Contents menu to navigate long pages, use the header Small-ToC and Tiny-ToC links to reduce the menu size. Possibly not that mobile friendly atm. Feedback, general contacting me, and IRC idling in #tnswiki on Freenode (web chat). See About for login and other info. / et / em
