By bringing Pownce “offline”, that is, not being tethered to a machine to do your … em … “powncing”, pownce will also be able to enter the same space as Twitter.

Sort of.

After all, in its current incarnation, Pownce will only be able to be viewed via mobile browser.  While such a site is still available for Twitter, we shouldn’t forget that many people use the SMS function of their phones to Twit away.  I suspect a great deal more people have phones that enabled for SMS than, say web browsing — although early adopters being early adopters, this proportion of folks who are *also* interested in Pownce and Twitter are likely to be much more equal than “normal” folks.

(just like more of them will also own iPhones and use Gmail, I’m sure).

[And following the line as from the above, in an emergency (like a catastrophic emergency), sending messages via SMS may be (this is total conjecture) more efficient and use less data than, say web browsing].
