1. Nielsen - Participation Inequality

   Talks about the web phenomenon of participation bias and introduces the 90-9-1 rule.
   In general, for websites that depend on user-participation 90% of user are lurkers, 9% participate infrequently, and 1% participate a ton.
   An example is a randomly selected USENET post is equally likely to have come from the 19,000 highly active users as the 580,000 infrequent users.

4. Nielsen - Does User Annoyance Matter?

   "Summary: Making users suffer a drop-down menu to enter state abbreviations is one of many small annoyances that add up to a less efficient, less pleasant user experience. It's worth fixing as many of these usability irritants as you can."
