I'll try to read up on this. Haven't been too impressed with the more vague OWS. My friends in Cinci have been working with homeless people, housing coalitions, impoverished communities, etc. on a real grassroots level (literally going door to door).
I assume this is similar by its name.
I was very involved in the first phase of Occupy last fall, and I think the indefinite occupations and vagueness were both very important at that time, as a public forum was a necessary first step for a people's movement. But I think at this point that more targeted actions by specific groups are the most effective use of energy.
Occupy Homes people have been restoring foreclosed families to their homes/keeping them from being evicted, with the goal of drawing enough national attention that the banks foreclosing them are forced to negotiate workable payment plans that keep the families off the streets. It looks like Brother Ali was arrested at the Cruz family's home, which has been one of the most documented ones recently.
