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 to navigate long pages, use the Small-ToC and Tiny-ToC header links on longer pages. Not that mobile friendly atm. #tnswiki on freenode IRC for feedback chat, or see About for login and further information. / et / em
