Scaling back social networks and adopting encryption

Cryptocat said it nearly doubled its number of users in two days after Snowden revealed himself as the source of leaks about the NSA's programs. Two search engine companies billed as alternatives to Google, Bing and Yahoo are also reporting significant surges in use.

DuckDuckGo and Ixquick both promise they don't collect data from users or filter results based on previous history. DuckDuckGo went from 1.8 million searches per day to more than 3 million per day the week after the NSA revelations came to light. Ixquick and sister site Startpage have gone from 2.8 million searches per day to more than 4 million.

Gabriel Weinberg, chief executive of DuckDuckGo, said the NSA programs reminded people to consider privacy but that government snooping may the least of an everyday computer user's concerns. DuckDuckGo's website warns of the pitfalls of Internet search engines, including third-party advertisements built around a user's searches or the potential for a hacker or rogue employee to gain access to personal information.
