Sorry you feel our tooltips are a gimmick - we used them because we felt it was the best way to convey the most information without crowding the screen with excessive copy.
The animated screenshot with the balloons feels very busy.
As I was typing this up, "Robby" popped in and asked me to talk with him. This feels a little too eager - and I'm never sure if these popups are real people actually contacting me (which makes me feel a bit uncomfortable) or just automated (which is annoying and makes you wonder if there's really someone there or not).
All in all, the site feels busy. Your 37Signals style "Premium Plans" page is a lot easier to follow, but it suffers the same balloon tip problem.
I'm not sure "complete protection" is a good two-word summary of the premium feature. It kind of implies that my data's going to be released to the public unless I pony up some cash...
It looks like it has potential. Sort of a simplified / low overhead Evernote.
The problem is that there are too many bullet points and not enough spacing between them.
Also there being two columns of bullets its easy to lose track of which bullet its about (left or right side).
