Guest post, guest post, guest post. I write guest articles for other blogs and also invite bloggers to contribute towards my blog. In this way network is built. Both the blogs get famous.
Content is the king - In the blogging world so diverse and big, you need to establish yourself with a distinction. the only road to it is good, original and valuable content. Be creative, different and surprise your readers once in a while.
A new blog should not add to the existing noise in the blogosphere. Do something outstanding to get noticed.
