I am indeed, but don't let ActivityPub support on GNU social be a reason to drop support for a different protocol (that happens to allow the same [but not only]). Let's maximize federation! :)

Btw, it's better to mention my loadaverage profile, social.hackersatporto.com is just a test instance and is currently using the ActivityPub branch as so it can't currently federate with pleroma, not sure why as it is working fine with mastodon...

P.S.: GNU social won't deprecate OStatus. It uses the most adequate protocol for the task and when one fails it attempts with a different one (if available in the same scenario). AP will fallback to OStatus in GS case.
