Thanks... After I started becoming quite disenchanted with Reddit I had been playing around with the idea of a aggrigator like hubski where you follow people instead of voting for content but never had the time or knowledge to put it together, so seeing the concept in action, as well as knowing that it works is quite fulfilling. After the first day though I have thought that it would be nice to know which users are feeding in new content and which are sharing (curating might be a better word) existing content. I say this only because I found myself struggling after first signing up figuring out who else to follow so that I'd get stream of content from various sources (and not just one user). Since the community is still relatively small I eventually got everything worked out, but it will be interesting to see how the idea scales when the number of posters and the number of "content curators" gets bigger.
Additional Thoughts:
Unfortunately this brings up an strong parallel to power users (who may or may not be a good thing for the site) and I quite like the process of discovery that happened when I joined, where I would follow and unfollow different users and topics to get my feed looking the way I liked it. So at the end of the day, I'm not sure if I actually want this feature or not, just thought I'd through it out there to think about.
