Nope you have 2 out of three correct the third is totally overblown. I don't have any trouble placing sites and have never begged for links er... did link development. I can do more with the content on the site then anyone can beggin' links and doing Social Networking and blogs. That kind of content rarely gets links from authority they get a lot of low quality links. I'll take a few quality/authority links over 100's of low traffic IBL's. Take the time you spend begging for links and build content and sticky items that generate links with no effort on your part. If you have to ask then... you don't deserve the link and the benefit will disappear with the next link algo update.
