x@Cheri Insightful post. I've tried Twitter a few times in the past but never liked it. Twitter is more of an automated machine for marketers and self-promotion. My wife, though, enjoys FaceBook but uses it akin to its original vision: keeping families in touch. Rita keeps in contact with family in Australia and the USA and neighbours. We have also helped cats find their owners again in our local area. I guess SM is what we make it. You can go deep or dip your toe. We're very much the latter.
