That's at least my first two reactions upon seeing this. Don't get me wrong, this idea is something I've wanted for a long, long time. Holy cow though, talk about a dark pattern: your credits method (and their 60 day expiry) has completely soured this experience for me out of the gate. I'm not going to sign up for a platform that continues to nudge me down a waterslide towards my wallet. Seriously, I'd probably rather have a subscription model for something of this caliber. If you want to attract a business crowd, you shouldn't implement a pay-as-you-go model. These companies want to integrate you into their SAAS stack and consider you a fixed-rate expenditure, not constantly worry about budgeting you into a part of their payroll.
