Thanks! That's definitely something that we think is missing and I hope you check us out. We started with blogs/scholarship/reddit/Q&A sites, but are adding Twitter/FB next. While many people have quality discussions worth aggregating and quantifying on FB, we were worried that it might dilute our initial product. I appreciate the feedback and hope you like it. Our next version - which is en route to completion - will feature data visualization of written content on iOS (which is currently available in an early form on the web profiles).
