So I want to start building some solid web 2.0 link to my main site and I was wondering about a couple of things in that regard: 1) To avoid footprints I'm assmuing I should use different emails for each web 2.0 account but what about proxies? Is it necessary to run each web 2.0 on it's own proxy? I was thinking about just getting a paid VPN like hidemyarse and use a different IP for my proxy sites than I do for my main site. You think that would be enough? 2) How thin do you make your web 2.0 sites? With the whole "content is king" craze that's going on I'm assuming we want to build a bit of content on the sites to create contextual links. So, how many word or articles would you aim for? I'm thinking 2-3k words per site? 3) How long do you age your web 2.0s before you start linking to you main site?
