I've been using it on Twitter for a little while now. I love the ability to find something I want to share at some odd hour of the day/night. I add it to my buffer, and it gets posted by @bufferapp at an hour that I think more people might see it. In the past, I would try to remember to do this manually, make little notes, etc. But, @bufferapp makes this so much easier.
Then, a couple of weeks ago, I found out that @bufferapp was adding facebook access. So, I contacted @bufferapp and they nicely signed me up for early access. Initially, preview images weren't showing up on facebook posts. So, I didn't use it much. That seems to be fixed. Now, I highly recommend you check it out for yourself.
Buffer for Facebook - Sign up for early access.
Anyways, thank you @bufferapp. You provide a very helpful service. There have been a couple of glitches here and there. Seems like typical growing pains, but these seem to be getting ironed out.
Hopefully, the folks at @bufferapp will add Google+ integration once the Facebook integration is complete.
