I find that interesting from Twilio's perspective: GroupMe was using Twilio to send SMSs (at least at first, but they didn't have much time to change the most important part of their service) and Twilio has recently added some VoIP components (Twilio Client) to their offer, which, even though doesn't compete directly with Skype, is covering much more bases than Skype is when it comes to integration in web or mobile apps. And based on some announced usage numbers from GroupMe a few months ago I imagine Twilio was/is making good money from them alone…
