Just building a good looking blog and writing thousand of quality post can not make you popular as Darren Rowse
and John Chow. Even they don't have got this popularity if they don't have created better relationship with another bloggers.Developing a better relationship is important for promoting your blog and getting lots of backlinks from them but not only this, it also give you the power to make your own and unique standing in the world of blogging.
