As a user I wouldn’t have liked one big app for everything. It’s an interesting idea to combine the two worlds, but I’m happy to use dedicated apps that can focus on each network’s unique features. Should also be easier to build and maintain that way.
And it doesn’t seem like there’s a lot of hope for the future of 3rd-party Twitter apps anyway.
This is the same guy who keeps relaunching tweetbot every new version just so you have to keep buying it.
