Why not combine those accounts together? Nobody cares about saving twitter accounts?
I'm going to create a twitter account about this.
Because they're actually run by different people. I run Save Clover Point (started when the wastewater treatment plant was proposed there) and Save Beacon Hill Park (started as a result of 24/7 sheltering and rampant crime) - the others aren't me. Social media can be an effective tool to raise awareness and affect change and when something works, expect others to take notes and do similar things.
