I'll be honest, I'll be surprised if Google Voice is alive in a couple of years. I've been an avid Google Voice user since before it was even owned by Google (back when it was GrandCentral), and Google have showed it little love, made virtually no new features or improvements in the past four years, and now buried it into Google Hangouts. Which is a shame, because I use it regularly and find it really useful.
It makes Google Reader look like a vibrant growing community, in comparison, which makes me think its ripe for cancellation, which annoys me. I've been using it as a forwarding / voicemail service for years across three carriers. Its very convenient, it just works.

Lack of MMS is a big one. No group text messages, with no notification to either the sender or the recipient that it was simply discarded. Aside from that, what are some features that you wish it had?
I'm somewhat hoping that Twilio comes out with something similar. They've already got the infrastructure set up, just need someone do a bunch of API work.
