@parados,
Don't you think that would be changing horses in the middle of the stream? It looks to me as though occupying abandoned properties is a full-time employment, whereas the author of the article which Tsar linked is talking about finding housing for the OWS people, who, one presumes, would still be putting their time in in protests.
I looked at the FUREE page for Brooklyn, and there was little about the nuts and bolts of occupying abandoned properties, but a good deal about social action activities. So my question is, do the OWS spend their time on social action protests, or on creating housing for themselves?
