A blunt statement, I know. The 90s were the worst times for computer development. Software AND hardware. If you lived through it, you’d know this. Remember dongles? Patches? Partitions? Help pop-ups? SCSI connectors and parallel ports? Sorry to revive these memories. Could you imagine what TiddlyWiki would have done to the world of computing back then?
All I know is that if there was a TiddlyWiki of the 90s, it would definitely be based on SGML or XML, while using almost none of the format’s features, but still overengineering a transformation pipeline.
There would also be a 
badge. It just had to have it.
Remember 20 years ago, picking up a book on XML. Writer was hell bent on text editors; hated code editors.
How do I get /give a cool badge??
