These are the news sources that I track for search and news sources related to search. I divided them into four categories:
Primary sources: Official word from companies or from employees who seem to give official words
Secondary sources: Feeds that I think are good sources of information
News sources: Good sources of news about what is happening (or what other people are reading in the case of Valleywag).
Related feeds: Feeds for search-related blogs that I want to keep track of.
You can download the RSS feeds combining these feeds if you want to import these into your favorite reader.
