I have some questions or observations..not sure which. Basically the tool is absolutely awesome. The issue I am running into is that a lot of the sites that have quality PR make you sign up to comment. Then the comments link back to your profile page. Obviously I am aware that this is not a fault of the designer, I am just thinking out loud here. So anyway, the comment links back to a profile page, for example at forbes.com. This is great as long as you can then link from the profile page at forbes to your website. I believe you can....anyway I imagine this can be helpful for your site, but it would be more so if you could then have the tool only scrape pages from forbes.com so as to increase the amount of comments you have on that site, passing the link jizz/juice/authority to your profile. The same is true for having to login to say facebook or twitter. If there was a way to sort the pages by how you have to login in order to comment that would be helpful. You could really juice up your twitter and facebook and also your forbes, guardian, and NYTimes profiles and then blast the hell out of those pages with some spam links...idk maybe that is not how it works???
Hope that made some sense somewhere...
