Curate, connect, and discover
The OP demonstrates something I've been noticing: our society treats homeless people as casteless unpersons.
Without even realizing it, we automatically categorize anyone who seems to be living on the street as an undesirable thing, best neither seen nor heard, and taboo to interact with.
Increasingly, this is how government and law enforcement are treating them.
Until we change our society's attitude towards homelessness, until a person's living arrangements are no longer seen as a reflection of their character or nature, the only change we can accomplish will be palliative.
"AnechoicMedia" deserves a good blog-lashing from @cavegirlpoems.
