That one has the Github Octocat icon I like, but hasn't updated to the new Twitter icon yet. Also doesn't support creating custom packages of just the icons you want.
No integrated git-push deploy (I know you can use a gem with an extra instance to do that, but still). No SSH into your app. No custom app. Extra runtimes are there, but old (Erlang, for example), and no idea how to use them.
The AppFog command line tool is very straightforward and even somewhat Git-like: http://docs.appfog.com/getting-started/af-cli. If the "af" gem is installed, "af push" is the equivalent to a "git push." You're right that it's not the same thing, but it's pretty handy.
Extra runtimes (newer versions of Erlang, plus Perl, Go, etc.) will become available over time. They're high priorities for our dev team, as are Redis, Memcached, etc.
Regarding git vs af, if I could use the git already installed in my computer, and by simply adding my SSH key into AppFog system, I could avoid using `af` gem and Ruby altogether. Otherwise, I would have to install Ruby just for this purpose. But this is just personal taste.
Other PaaS such as Heroku or OpenShift allows you to set up a custom app. For example, you can create your own app type in Heroku's cedar stack with buildpacks, or the DIY app in OpenShift with supports for hooks.
Erlang probably isn't on the top of the priorities list, but I'm looking forwards to it.
The key thing for the new channels is that it's the first expansion outside the screen and into the physical world. A lot more to come in that area, stay tuned.
I'd be a _lot_ more excited by the update if I could add my own custom channels for less popular sites, or use other custom channels that other people have added.
It'd easier for a repo hosting service provider to provide an integrated planning tool. It'd be easier for customer too. Of course, only when they do it right.
I love Trello, but it's supposed to be generic, and thus, not easy to use it as a Kanban board (limit number of cards per list, etc) out of the box.
