Actually your site seems mostly to work. It does seem slow. That might just be my browser taking a long time to work out what to do with what you've sent.

Not sure I'd use the service. Like most people, I guess, I've already got systems that scratch the itch, and I'm reluctant to put important stuff in someone else's control. I would think that not-yet-established people would have fewer reservations.

If I think of more comments, I'll let you know.

EDIT: The reason for putting some items top right and others on the left is unclear to me. I'm not sure which to look in first when I want to do something, but I'm not sure what. Probably with practice I'd know whether to click "here" or "there", but it's a long way to move the mouse between them. It's a small, picky, subjective design issue.
