Google Reader is just too easy to use. Hours disappear browsing through all interesting news and blog feeds. The key shortcuts works great, it's easy to star or share links and all embedded media just works.
The only difficulty is to sort the flow of news and just get the best most interesting things. To avoid information that you don't really need. I'm guessing this problem will just continue to grow just as quickly as the flow of detailed information does.
If someone missed the flash movie called Epic 2014, released in November 2004 by Robin Sloan and Matt Thompson you owe it to yourself to watch it. These guys were way ahead of their time doing this. Impressive!
