Thanks for the heads up on chunews. I was having some trouble finding similar projects to judge where I should focus development. How many users did you get?
As for linkedness, I'm going to do a detailed blog post about it sometime, but here it is in short:
Use the HITS algorithm to get hub and authority scores for each ___domain. Pages are related only if websites with higher scores link to both of them. This makes spam much less of a problem (I think!), and will make for some interesting search algorithms that I haven't quite implemented yet.
I was more my attempt at recreating TailRank when it closed down (since I assumed that it couldn't be that difficult to write). It just seems to overlap what you have there quite a bit.
Not many users. It tends to get a lot of SEO traffic though (usually breaking news stories funnel through it pretty quickly and you see a large spike) with anywhere from 50 to 500 uniques a day.
Ah interesting. Chunews does statistical word ranking on each article it pulls down to group similar stories together. From memory it uses links as well but in reality since it checks exact links that never affects this.
One of these days I may iterate on it but for the moment it shows me whats happening in the world at any point which is fine for me.
