+1 agree that it is not money. However, if it was a pure commodity then it would necessarily require some (even minimal) use value, beyond an exchange value. Right now bitcoins have a 0% use-value and a 100% exchange value (eg, if they could not be exchanged for something else, they would merely be taking up space on our harddrives and are inherently useless, like random chunks of data).
But even if Bitcoin's exchange rate does not mean that bitcoin is not money, if I think Bitcoin can also be used to buy some of the things we want, maybe not many companies are currently developing their business to make payments with Bitcoin. But that's just my assumption, correction if I'm wrong, because we all also learn together.
