I am working on my own help authoring tool "with blackjack and hookers" :) It has a cool name: Helpinator.

I upvoted this because everything is better with blackjack and hookers.

Reminds me of "Doppler" by Erlend Loe :)

Exactly what my family said :) "Your doing a Doppler!"

I think there are two types of users in this case - "consumers" and "researchers". Social news are good for "consumers" with their usage pattern "Read-Like-Forget". They consume to feed their hunger and nothing more. "Researchers" carefully select trustful sources and follow them, they need a tool that allows to keep track and never miss important info. "Researcher" pattern is impossible in the "social" noisy flood of news.
