I am a newbie. I would like to build a private web2.0 blog network.I have few doubts, Please clarify these I have created 210 email accounts on 4 different free webmail services. 1. I have a list of 210 web 2.0 blog sites.Should I use 210 unique emails to create accounts on these 210 sites or is 1 email enough to create account on these 210 sites. That is 1 web2.0 * 210 emails = 210 different accounts on a single web2.0 or 210 web 2.0 * 1 email = 210 accounts on different web2.0 2. The total number of web 2.0 accounts will be 44100 [ 210 x 210 ]. Initially I would like to go with 210 * 5 = 1050 blogs .Is building these 1050 blogs with generic content is enough , so that I can add article related to any niche, or should I feed these blogs only with a particular niche related contents. 3. What are the points to be noted to avoid foot prints ? . Thanks in advance .
