Does the inflection rule still work the same way with proper names?

I don't see why not. If you turn it into a verb it would seem unsporting not to let it behave like other verbs.

Therefore we doubled the 'k' above. We also added hyphens for clarity. And camel case for clarity. Please lord let it be clear now.

Yes. If Twitter had been named after a guy named Bob, then the past tense of the verb for posting on that service would be "Bobbed," not "Bobed."

Ok, thats fair. It seemed weird at first that there could also be someone named Bobb, but I guess that would be Bobbbed.
