As long as there is data, scraping is profitable if you can get creative with it. The power is in the ideas. For example, look at SpyFu. They built a huge business upon screen scraping google results.
You can PM me if you want to talk about scraping, because I'm currently undertaking quite a few scraping projects.
That tool looks great, how do you integrate the proxies? Are you using any special hosting? Or just a shared one?
Any thoughts on all of this, anyone?
