Like what though - if you have enough information to generate a social graph, and you have access to the firehose, then you're going to be have what you need. Social scientists will often use a sample set as a very acceptable proxy for full data set analysis (http://www.insna.org/PDF/Connections/v18/1995_I-1-9.pdf http://www.insna.org/PDF/Connections/v18/1995_I-1-9.pdf) There's little evidence that the Twitter guys have come up with an outstandingly amazing reputation algorithm and that this niche has been filled. The opaqueness of Klout doesn't fill me with confidence that their methodology is valid or truly meaningful.
