Grouplite - a web app from the ashes of startup failure.

May be cliche, but when people buy a drill they don't want a drill-- they want a HOLE. When people sign up for your product they have a problem that they want to solve... What's that problem? I'd simplify your home page, focus on value statements, screenshots, and examples.
(just my 2 cents)
The home page slowness is fixed.
You're right about the lack of intelligent marketing on the homepage. Frankly, this was a problem with the earlier startup as well.
The initial load time in Safari is significantly longer than firefox (although refresh loads are much more speedy). You might have to wait 10-20 seconds.
