tiddlywiki.com serves the needs of several distinct but overlapping groups of users:
- It is the landing page first encountered by prospective users
- It is the online demo for prospective users to explore
- It is the online documentation reference for current users
- It is the community test bed for quick tests and proof-of-concepts
And perhaps there are more. The point here is that any redesign should not unknowingly make tiddlywiki.com less useful for any of these groups of users.
