Another Search Blog
Search and its derivatives (contextual, behavioral, etc) is one of the big investable markets in the venture/tech world right now and a lot of people are paying a lot of attention to it these days.
I am a fan of John Batelle’s Searchblog and rarely does a day go by that I don’t read John.
I also read WIN’s Search Engine Marketing blog from time to time.
And Majestic Research is a great source of information on the search market even though they don’t have a blog.
I like what I see. I’ve added it to my feeds.
