I've found previous version of TiddlyWiki too limited to use (couldn't include images or other media on a page easily). I'll have to look into the latest release and see if they've fixed any of that.
I've since installed a full-blown wiki package (https://www.dokuwiki.org/dokuwiki) on my home server, but it's not a solution for everyone, especially if your PC skills are somewhat lacking, so I'm always looking for something new to recommend to friends.
Recently, I ran across Scribbleton (http://scribbleton.com/). Easy to add text and images, works on multiple platforms, and fairly light-weight.
