So, I am looking to build a series of micro-niche sites and would eventually turn them into a mini-PR network myself. (Assuming I got all whois, hosting IP, all other stuff covered for building PR network) Now, I recently came across plugins like wp-twinbuddy or some sort, you get the idea. I am wondering if using those will leave footprint, and destory my perfect idea of 'footprint-less' network? P.S: No, none of my micro niche sites will have adsense on it, so they arent interconnected either way. Please advise. Thanks.
