Ask HN: Those of you who signed up for App.net. Are you actually using it?

I am the same as you, signed up a dev account. At the time I had no real intention to use it, but I wanted to support the idea.

If I do decide to do something with it, at least I have my account!

Yep, I had a similar train of thought. I liked the idea, and could spare the $50 to help them on their way.

only really via IFTTT, though think I could migrate as most of the people I care to follow on Twitter are broadly doing the same, so whilst I am not actively using it, the ability to jump ship a lot easier is there

Signed up, reserved name and I am now waiting for it to be something useful.

Yup, same. Bought / reserved the username 'just in case', nothing more.
