You should expect your readers to be lazy - but you are not allowed to be lazy. It would cost you nothing and only take you seconds to add the source link so that readers here also take a look at your site.

You are wasting an opportunity because you want people to act according to your ways of thinking, instead of trying to guess how they think and tailoring your methods for attracting them. Yes, you give your link on your blog header, but not many will bother to look there, it is easier to just move on to the next message.
