I absolutely adore Social networking buttons! I usually have them strategically placed throughout my pages. When used correctly, they can provide a whole new selection of readers, or keep bringing back ones that you have had. I find the best places to put them are top left or right, eye level with the top of your post, and at the beginning and end of your posts. (Me saying this doesn't mean that you have to put them in all those locations, but those seem to be the most natural placements)
