For someone to connect to a Colony through a standard web browser, it seems they'd need a plug-in like MetaMask ( https://metamask.io/ ) and I wonder how this might limit who uses Colony?

And then would people need to have some tokens to interact on a Colony, and they'd buy the token on an exchange? That requires another account on something like Coinbase, and a wallet?
Once someone has it all set up, a wallet and a secure way to store their private keys to access their tokens, it could be pretty easy to interact with a Colony, but I imagine for there to be network effects on colony.io this might require some catalyst? Maybe an external event, some financial crisis to move a large enough number of people around the world to using crypto?
