I like the idea, but a lot of things annoy me.
- The navigation doesn't work well for me, it's not intuitive (you need to really work hard on that)
- I can't resize text fields
- I can't drag and drop stuff around freely due to the navigation limitations when d&d is enabled
- A lot of text doesn't fit into the text fields, they should grow vertically or you need a scroll bar
- I can't adjust the font size
- Pictures either don't work at all or I can't figure it out
- Same for video / sound
- There are no traditional forms (buttons, input fields, ...) to generate POST messages
- javascript, XHTML, CSS etc all thrown away
- The presentation is rather crude, it looks like a hacker project
- Too much stuff on the screen, can't be helped, I suppose... Maybe use an LoD algorithm to not show a percentage of keywords when a cloud is far off?
