I enjoyed the Mind Touch experience apart from a few points.
A new article seems to have some confusing junk in it. I think it
generates the introductory message, but it was disconcerting to see it
in a supposedly wysiwig editor. It was {{System blah blah}}. A minor
disappointment was that it did not integrate image uploads in the image
adding gui. Other than that, it was quite intuitive.
I've signed up for the
grouppatternlanguage.org site, but have not been
accepted yet and it's been over 24 hours... I may not have put enough
in my initial profile for them to see me as a real person - but the
www.wagn.org has a sandbox. It's much less intuitive - at least at
first glance. It does require figuring out some syntax. And it's not
intuitive what happens once you've created a card. Maybe I'm lazy, but
I'd rather not spend a lot of time reading docs to figure out things. I
think I prefer MindTouch.
