I use TiddlyWiki for… everything!
- personal knowledge base and notes
- a way to generate my personal webpage through a “Public” tag. This lets me generate the wiki with things I want to share, and keep the rest of the wiki private. This includes an RSS feed using @saqimtiaz’s code here Has anyone generated an RSS feed from TiddlyWiki?
- to back a custom sidebar on my computer, with shortcut links, weather radar, etc.
- to power my phone / tablet wallpaper with similar information
