A useful poke

I am trying to use Facebook more. I do not have a lot of use for the "poke" tool, which seems a bit childish. I wonder if it would be good to use the Poke method for content? What if you sent someone a book you thought they should read or you wanted to discuss. Sent a link to an ebook? Then they didn't reply. You might poke them about that post of content, not just generally?
