  • YouTube Blog: Inside User Research at YouTube
    We still have a lot left to learn about how people use YouTube, but some things have become clear. One of the most important findings has to do with the difference between the large group of users who are on YouTube simply to watch videos and a smaller, but very important, group of more engaged users — often uploaders. The latter group will, unsurprisingly, care about details like how to make communication with their audience easier and more effective, how to grow their audience, and even how to make money on YouTube. The former, on the other hand, want as simple of an interface as possible: "Just let me watch the video, please!"

  • Facebook | Facebook Data Team: Distributed Data Analysis at Facebook
    Today, Facebook counts 29% of its employees (and growing!) as Hive users. More than half (51%) of those users are outside of Engineering. They come from distinct groups like User Operations, Sales, Human Resources, and Finance. Many of them had never used a database before working here. Thanks to Hive, they are now all data ninjas who are able to move fast and make great decisions with data.

  • FT.com / Reportage – The rise and fall of MySpace
    The two sides differ profoundly over where responsibility lies for the site’s decline. Former MySpace executives say News Corp dragged its feet over implementing Ajax, a program that allows users to send a message, an e-mail or to post a comment on their friends’ pages without having to open a new browser window. Facebook was quick to embrace Ajax but MySpace did not follow suit, partly because to do so would have reduced the number of page views the site generated and therefore its advertising revenue. “It would take five steps to post a comment or send a message, so five different pages would open,” explains another former executive. “There would be ads on each of those pages, so we were making money. We went to News Corp and said: ‘We want to change this but in the short term our revenues will drop.’ It became a long back and forth. [They] were pushing back – they wanted to make sure we weren’t going to drop our revenue numbers.”
