Whatever products you sell, they will not get sold without a little marketing strategy. #advertising
This includes running ads on your site, and of course, social networking. Your network can reach people you do not even know and boost your sales, and besides, someone needs to put something online besides pics of cats with sun glasses.
Sharing your product with your net family only takes a few secs and the potential for future sales are worth the effort, so go ahead, share. Share the gosh darn heck out of it.
