My idea is this:

In a place where media's biggest issue is about trust and credibility, why not infused a media based type of government services that features public real time information? i.e weather system, public announcements, government news and current events, etc.
There will be a mutually exclusive relationship of the government and its trusted constituents which the main benefactor is the public masses. Trusted and credible information will be rewarded among users who can provide. Users can launch fundraising or crowdsourcing for a cause in terms of a calamity arises. In that way also, corruption will be avoided, rewards/funds will be directed to the affected users.

Conclusion: If you think deeper, the most important information a social media can provide is about safety. A single mishap of information can create drastic changes on how to people react and adapt to the current situation. I'm basing all these ideas with the current situation of the Phils. and probably to any other disturbed countries.
