I love the way: On Likes, Faves and Sharing thinks & practises the different micro connections on the web. I wonder if a nuanced, formalised set of interactions would be better than a carefully reply.
IMHO, the best way of registering thanks and supporting the efforts of the author is to take a few moments and to write a meaningful reply — perhaps in a comment, or better yet perhaps by making your own (micro) blog post — and linking back to the original.
