–Does it look like they follow a content calendar?
There is a Facebook post, and usually no more than one, most weekdays. This appears consistent with a flexible daily posting cadence. Twitter posting appears more erratic & reactive, including retweets & responses.
–How many people contribute to the social channels?
There are several comments, dozens of shares, and hundreds of likes for each of their Facebook posts. There are only a couple of other one-off, institutional interactors on their Twitter feed.
–What is the message they are getting across?
That the homeless only need help to climb out of a low point in their lives.
–Who are they trying to reach?
Potential donors & volunteers.
