Graze ▶ Worth it? What do you think?

Options
As someone who does have a certain tendency to, well, graze, it's hard for this not to sound appealing, particularly with all the options, etc.! I've heard folks mention that the portions are small, and other like things, but for those (US-based in beta, or abroad where it might be more established) what do you think? Worth it? What are your favourite things about it?

Maybe it's just that part of me that likes being in on beta things (Gmail early adopter, anyone?) but I'd really like to check this out, and wondered if anyone might be able to PM me an invite code? You've got my word that I'll pay it forward here to some lucky soul(s; I've heard mixed things on whether you get more than one go on an invite...) once I've got mine in hand! It just sounds exciting. :)

Also looking for more friends here as I hop back on the wagon! <3
