My favorite website by far is TechCrunch. It is a site started by Michael Arrington a few years ago, and is dedicated to reviewing new Internet products and services. I found this site last year and now read it daily. TechCrunch showcases new and existing companies along with their products or services. They have tackled everything from Google to LinkedIn (among the well known), to smaller startups and not so well known companies like Lingoz. Brutally honest opinions are given on each company and their offerings and where the folks at TechCrunch see them going, and what kind of value they bring to the table. Their site CrunchBase lists all of the companies they have profiled.

From a recruiting standpoint, I have found hundreds of new websites through TechCrunch to explore and new products and services to aid in sourcing specifically. While not a site specifically aimed at recruiters, you will see huge value if you take a few minutes and read through some posts.
