I'm thinking about building a lot of web 2.0 sites. I would then repost the same content on them as what's on my site. I currently do this on social media. The goal is to get traffic without worrying about search engines. Do the web 2.0 sites themselves have enough traffic to make this worth while? I would like to do this on a large scale, but I'm afraid that I'd be wasting my time. I just want to expose new readers to my content.
