Do you know how few people still know about it?
Here in europe for instance it's not that known.
I think that success or failure of bitcoin depends not on average, small users but on ''big'' merchants.
If big online companies accept bitcoin as payment tool, and through this process bitcoin become mainstream, many other people will naturally follow and start using it.
Why not?
But, right now, average user don't have many opportunities to spend bitcoin and its value is very unstable.
