Hmmm, interesting... I got an IPad from Santa... Having fun playing with it. Hunting through apps. But, help me out here... Why does one need an app to do some stuff like adding to your blog or updating your status? Wouldn't it be easier to just go to the webpage?
So I have a FB friend page for the DI Flyby primarily so that I can use that account to setup a fan page for the EPOXI mission (rather than using my login which is already being used for fan pages for the UM Observatory and MAC)... And now I've setup twitter links between the accounts. And it's a mess!
So, I think that when I update the EPOXI fan page, it updates the spacecraft twitter (cometexplorer) which is setup to update the DI Flyby friend page... Doesn't go the other way though. I don't think. I've got a few months to experiment, but I gotta get all that straight before the encounter in November.
