Any suggestions on how to build an online network or presence (Apart from people I know on Facebook and Myspace) so as to get as much traffic as possible to my blog or online properties? Why I am asking this is because I have seen in the past that many people launch their blogs/websites and within a couple of months they get hundreds of readers, if not thousands. These people must be already having a powerful online presence and when they launch their blog, they get massive amounts of traffic. And I have not seen them spending any money on PPC or any thing as such. What do they do to first build their network? Any suggestions/Tips on how to do the same like a professional?
