Mark S,
Didn't you tell us that just the name tiddlywiki prevented people using it?
Roam research seems to be popular and loved, but having to sign up, be put on a waiting list and soon having to pay 15$ a month seems to make a lot of people wanting to try tiddlywiki (Stroll, Drift). Not having to sign up, no waiting, go straight to download 24/7, Not all is in the name.
I love to watch those youtubes, tiddlywiki mentioned with no giggling.
