If anything, bloggers are being spoiled rotten by the variety of tools (most of them free) being developed. The latest service is Sphere.com, which is finally entering the ultra-competitive blog search market after a long time in beta. TechCrunch has all the details about Sphere's features (when does Michael Arrington sleep?). Sphere has also raised $3.75-million in venture capital but Om Malik makes a good point that company is going to need more to compete against Technorati, Ice Rocket, Google, Blogdigger, et al. Still, there's always room for a new player with an edge. After all, Google entered the search market as a nobody and now rules the world. Sphere's financing comes from Hearst Publishing, Trident Capital and About.com (the New York Times).
