Four short links: 7 January 2011

User Experience, Big Data Case Study, DimDim Acquired, Secret to the Web

  1. Users Can Self-Report Problems — users self-report 50% of the problems that professional usability testing uncovers, and they find problems that usability testers don’t. (The other way to look at this is: self-reporting only finds half the actual problems in a site)
  2. The Learning Behind Gmail Priority Inbox (PDF) — challenges faced by Gmail Priority Inbox and how they beat them. Priority Inbox ranks mail at a rate far exceeding the capacity of a single machine. It is also difficult to predict the data center that will handle a user’s Gmail account, so we must be able to score any user from any data center, without delaying mail delivery(via Hacker News)
  3. DimDim Acquired by Salesforce — congrats to the founder, who was an OSCON speaker, and his team. The open source remains, but will not be contributed to by Salesforce. DD Ganguly, the founder, is a good smart chap and I look forward to his next project.
  4. WWIC — As Tim said when he forwarded this around: This is absolutely brilliant. Think deeply on it. Act on it. (via Alex Howard in email)

    It’s too bad DimDim stopped contributing to their open source project back in 2006 or 2007 and called themselves an open source company right up until the sale.
