For now, nothing - but long term to stop the POB token becoming just like the others (just being used as a tag for an extra tokens to be sold on receipt) we will need development.

Another long term use could be to pay towards having the token listed on an independent exchange rather than hive engine.

It really is a long term play this one, but the token has a far better chance of progress as a long term prospect if we have funds available for development, this way we can save towards that without it actually costing anyone.
