Integration with Geckoboard
Geckboard is a popular system to display a variety of metrics via a dashboard for the room. I understand this can probably be done with the API, but if you did a direct integration with them I'm sure you'd see your sign-ups increase since you'd be on their integration list.
Just my 2 cents worth. :)
Yeah, having direct integration with geckoboard would sway me, we use geckoboard for all of our stats and cant really work with something that doesn't work with GB, even though we like the testing we've done with updown.io.
