I had no idea there was this much community effort around TiddlyWiki, but looking around, there are several companion tools for it. I've always thought it was a great piece of software, and obviously others agree.
Used it in a previous ops support gig to build up a mini knowledge base of canned issue responses / topical oneliners - we couldn't install software but could save network drive files; tiddly kept my response system flexible & portable between systems - definitely recommend for this use case
