I am also a TiddlyWiki user. I use it as personal note taking + bookmarking + daily reading log. The best feature it has is a Wiki feature, not any TiddlyWiki feature: backlinks. I could make the backlinks show up in the footer of every page (tiddlers) and this reminds me connections I might have forgot. Tiddlywiki is also a great system for bookmarks. If I read something written by or about,say Roosevelt, I just add [[Roosevelt]] and I click on the link and just add a one line description like: Roosevelt was a [[US]] [[president|POTUS]] <year> and it will create a nice connection to the POTUS page and the US page. This is different from restrictive categories.<p>I keep software links, configuration, track-list for stuff I want to track (great new product/bookmark/book/service, just add [[TrackList]] when creating that page and can see it later in the footer of my TrackList page. Most Wikis can do this, however, in TiddlyWiki it is easy—no need to edit PHP files or plugins; it has a nice filter syntax that allow anything to be queried in a myriad ways tags, date, custom fields, title and so on, I just place that filter right there in the text and get the results.<p>It also supports other syntaxs such as Org-mode and Markdown if you use them; in retrospect I should have chosen Org-mode as an Emacs user, it would have been easier to get the data to other programs.<p>Couple of problems I face:<p>+ No converter to convert files to other Wikis or formats:<p>Not a TW problem, Pandoc and other tools cannot convert this to say, MediaWiki or DokuWiki. So as a non-programmer I am stuck with this as of now. But I am slowly trying to make work a Perl module[x] to convert the HTML to wiki form.<p>+ Static pages has awful URLS:<p>It double encodes the URLs and it is filled with "%2520". I wish they make a setting to replace that with hyphens or underscores.example page:[y]<p>If they could get this to work I think this has the chance of being the best static site generator. Easy to use and extremely customisable (or may be I am coloured by my non-programmer experience with static site generators).<p>+ Duplicate titles:<p>'Notetaking' is different from 'notetaking', so occasionally, I link to a non-existing pages for less frequently linked pages; there should be a setting for naming policy.<p>+ Data corruption:<p>I've seen few cases where people lost their data completely. TW warns about this in their page and advice people to use backup (I backup it to Dropbox).

Nice bunch of people.
