First impressions: I really like the overall look & feel of the site: approachable, modern, clean, and not needlessly "web 2.0"

I have trouble knowing from your messaging who your target audience is, and whether I'm in it. E.g. needs for someone who travels casually and who is accruing miles towards a particular vacation would be very different for someone who travels for a living and has dozens of accounts to keep track of.

For me, I've mostly standardized on United Mileage Plus and therefore make sure that any reward programs I participate in are compatible with United's program. Therefore, United's site serves as the aggregator for all my mileage/reward programs.

I'll sign up and see how it goes.
