|I couldn't resist. lol.|
Honestly, I am not your best source of information for this topic. I haven't really gone out of my way to build a relationship with a particular publisher, author, blogger, or bookstore. I just kind of coast along, blogging away, and hope things will fall into my lap.
Does that make me totally lazy? Yes, yes it does.
I have on occasion sent a request letter to a publisher for an ARC, but have never gotten any response. I much prefer to be approached by an Author or Publisher for a review or to join a book tour so I don't feel like I am begging for books. =) However, I am an avid user of NetGalley and LOVE that site. If you are a book blogger and haven't looked into joining NetGalley yet you should really go check it out!
I don't think there is really any kind of secret to approaching bloggers or authors... just be yourself! If they like you great - if not - life goes on. Right? As I have said before, generally everyone is super friendly and as long as you are respectful and honest you will find your niche in the book blogging world!
