Digg Vs. Reddit Vs. Del.icio.us

I have been a long time user of Digg. This is the reason that I primarily started my 'interesting' category of blogs on Digg stories. But then, of late, I have been following three user-added news content services : Digg, Del.icio.us and Reddit. I thought, I would hence make a comparison of all three. Well, the basic difference I can find out between Digg and Del.icio.us is something similar to the difference between Wordpress and Blogger(beta) blogs. While Digg offers to choose a category for your blogs, del.icio.us only lets the user choose the tags appropriate for the story. This is in a way disadvantageous to a visitor seeking for information. Suppose I am looking for football, and all those who have saved a particular story have tagged it under soccer, then I might possibly miss out on that story. Reddit is worse. It has no way to categorize the news. It is simply posting news. The closest to having a category are the subreddits. Another important aspect is the usability of information. It definitely helps if you know what to expect before visiting a link. Digg is much more superior in the sense that it provides a brief note on what the story is so that the visitor may decide for or against visiting the link at all. Third is community building. I find the users on Digg are much more knitted than those in the other two. One straight simple reason: the ability to communicate. Del.icio.us has simply no way for users to talk to each other. Not even a comment on an article. Reddit allows commenting, but I find the Digg comments much more sensible and fit for finding online buddies. Fourth is SPAM. Digg has a strong backup to spam. In fact, not all posts that you want to be pulled down are spam. Duplicate and senseless stories are also one. Digg has a good range of reasons you could choose for pulling a story down. Reddit offers to report the story, but then, it is much more work for the people at Reddit to go through each and every link reported. Well, at del.icio.us, life is cool..there exists no provision to even report a genuine spam. Fifth on design. It is simply a study of the navigation and user-friendliness. Digg no matter looks good. The only factor that goes against Digg are the ads, which I believe is the reason Reddit and Del.icio.us look the way they are. Absolutely no ads. So, based on these info, here goes my ranking: 1. Digg 2. Reddit 3. Del.icio.us
