What about an activist app?

[marym625]

Maybe something like this already exists but I can't find it.

I had a poll up about what we have to address to stop our quick slide into the downfall of our country. In the thread it popped into my mind we should have an app for activists that would be something like Grinder. (Not meaning we end up doing each other ) But a way to connect, share ideas easily and quickly. To cause meet ups and promote protests, rallies, brainstorming, etc.

Eleanors38 said, "if it can replicate the legitimacy of, say, a Walter Cronkite. I believe any effort should be accompanied by regular get togethers, the in-person variety. Instead of ponderous conventions, a series of local/regional social & working events (wk. ends?), with maybe one culminating yearly event. It doesn't all have to be in one locale, but many in one day can be tied together by the net, giving real time-certain unity, and instilling anticipation for the next gathering. 

These are nuts & bolts, but something has to be done to break through the malaise."

I am a computer idiot and haven't a clue how to do this. I really think this is something that could help and get people who might normally not, to be involved.

Any thoughts? Suggestions? Does this already exist?
