Public Ideas — Can You Bring My 71,000+ Facebook Followers Back to Life?

Obvious one would be to get sponsors - if you don't have the time - partner with someone who can do some outreach and get you some deals for sponsored posts and get a % of them? It's a journalist kind of page - you must have some students, universities that can be interested in using that audience in some way? Maybe worth exploring that?

I face this issue, basically I started my own page but not able to give proper time, so I decided to automate my whole process, like content creation, commenting, posting etc., so, I am currently working on building the system, and may be it can help you out!

Before trying to monetize it, I'd be curious whether the audience is still there. What about posting a simple poll asking followers which topics they want covered now? With 71,000 people, even a small response would tell you something. You might discover that the audience has changed interests since the page was active, and that could determine what kind of partner makes sense.
