Although i am personally biased to support Roame,
(as they started small and expand in steps without overpromising)

I can only tell you that point.me seems to have every major blogger on board to support it and with some financial interest
So actually onemileatatime, viewfromthewing, godsavethepoints and others big names...

And have a tendency to overpromise that besides G-d's greatest creation is the woman, sliced bread and plumbing, it is now point.me

Although above big names tout that point.me has a special relationship with airlines,
The current events seems that some competitors are using datascrapping which seems to annoy especially AirCanada, United
And there are even some airlines that block datascrapping......
