I'll just list 3 reasons. (Alternatively just click anywhere to skip this, you maverick.)
You spend your day flipping through different Social News Aggregator Sites and their linked content. Desperately trying to find something interesting amongst their many jaded and heavy handed ranking algorithms. Articles are brought in, and each site has their collective weighted, to allow a good mix on the front page. Have it all in the same place, sorted and cross-site-ranked against each other.
Data regarding the submission itself
Each Aggregator site has an opaque rule system which affects the links you see. SageBump offers universal icons to help you understand the quality of a post, by giving you the reason for its rank.
Sagebump handles moderated content lightly, minimising the damage caused by over flagging on the source sites. SageBump reduces "penalties" producing a better spread of articles.
Login to reddit then click here to get your custom Reddit front page listing feed URL. Then just copy and paste the URL into sageBumps' Reddit Custom Feed box.
Login to StackExchange then click here to get your custom StackExchange, then click on "Filtered Questions". At the bottom right will be the RSS link to your filter. Then just copy and paste the URL into sageBumps' StackExchange Custom Feed box.
Enter this URL http://slashdot.org/index.pl?content_type=rss&logtoken=$logtoken - replacing logtoken with your subscription token.
The usual parsing feeds, throwing them together, then *lightly* applying to each sourced group of articles their corresponding customised sageBump algorithm.
The details of how to implement a fair sorting algorithm to adjust for HN article flags can be found in the link below. For Reddit I use a slightly modified version. Once the received article are applied their corresponding algorithm, they are merged together. Each group is applied a further weighting, simply to get a nice mix on the sageBump page.
Choose which website feeds you get, then customise these further to only show the articles you want. Sagebump is THE most powerful tool to get the data you need. Amongst the options, you can also specify which Newgroups to display seemlessly alongside your posts. New feeds will be added weekly, but please feel free to recommend a feed.
How did I choose the default feeds? To please the Technocracy I researched, alot. I also used this excellent thread, and this one
