Ryan Singerrjs: “Most writers try to take their personality out so it sounds proper. I like the goofy ones better.” http://bit.ly/dC9NTl

uptonicuptonic: When you buy something from the cheapest source, be prepared for subpar customer service.

Matt Linderman@mattlinderman: According to cookbook I have, “macaroni” used to be slang for cool. Way better than “bananas” I think. Gonna try to bring it back.

Sam Stephenson@sstephenson: If you’re not working on the problem, you don’t have all of the information.

DHH@dhh: Great ad for the Kindle: http://bit.ly/aAJrXR—I’ve tried to use the iPad in direct sunlight, it’s completely useless.

Jason Fried@jasonfried: There are examples of everything.

Ryan Singerrjs: Amazon should show the spines of books beside the covers so you can easily judge how fat or thin they are.

Sam Stephenson@sstephenson: All this energy spent obsessing over the tools used by successful people would be better directed towards studying their successes instead.
