The Synopsis – Opinions wanted!

The other day I had a conversation with fellow author David Knight¬†regarding synopsis for non-fiction books. Long story short, there is an opinion floating around the cyber universe that beginning a synopsis for a non-fiction book with the book’s title is “amateurish”. Example (synopsis for the fictional book Trading with Trolls):

Trading with Trolls takes a look at how you can trade with the hairy creatures who live under the bridge. Though trolls may look scary, inside they are soft and warm and filled with the same hopes and dreams as the rest of us. One only has to discover what a troll is seeking…

etc. etc.

So what do you think? Does starting the synopsis with the title of the book mark it as “amateurish” or are we just sweating the details too much? I’m interested to hear your opinions!
