• Search Blogs with Ask.com: There's a new blog search engine in town from Ask.com. The best thing about it? It's wonderfully intertwined with Ask's (in my opinion) best property, Bloglines.
• Opinmind: Opinmind is a unique kind of blog search engine. It not only searches blogs, but it searches those blogs for opinions expressed on whatever subject you might be looking for.
• Sphere: My overall impression of Sphere is that it's a blog search engine with some great features, relevant results, and an excellent overall user experience.
• Technorati: Technorati is a real-time search engine dedicated to the blogosphere. It only searches through blogs to find exactly what you're looking for. At the time of this writing, Technorati was tracking over 22 million sites and over a billion links, a mind-boggling amount.
• Google Blog Search: The sheer simplicity, ease of use, and fast delivery of the service, which is really a hallmark of all Google's offerings, is going to draw a lot of converts who don't want to wait around for clogged databases to finally get through churning results.
• TalkDigger: TalkDigger is a search engine that finds what links are talking about links. Make sense? Well, in a nutshell, TalkDigger lets you enter in a URL, and then goes out and finds what sites (from a variety of different search engines) are linking to it. It's a conversation search engine.
• LJSeek: LjSeek.com is a search engine dedicated to only sifting through the LiveJournal blogging community. If you're a dedicated LiveJournal user or just looking for information, you'll find that LjSeek comes in handy.
• Daypop: With Daypop's blog search engine, the user can "search 59000 news sites, weblogs and RSS feeds for current events and breaking news." Daypop also has a cool Blog Archives feature; see what was buzzworthy in the blogosphere in days past.
• Blogdex:A blog search engine and a "finger on the pulse" kind of deal; Blogdex is put together by MIT and is a service that "tracks the diffusion of information through the weblog community."
• Technorati: Technorati is a blog search engine that is a real-time recorder of what is going on in the blogosphere. At the time of this writing Technorati was tracking a whopping 20.8 million sites and 1.7 billion links.

• Blogwise.com: "Blogwise is a site about developing a portal to blogs around the world, efficiently, quickly and nicely." More of a blog directory than a blog search engine, but they do have a site search available and an impressive amount of blogs in their directory (over 100,000 at the time of this writing).
• Ice Rocket Blog Search: Excellent blog search engine that includes the option to search by link. Ice Rocket also has a pretty good advanced search page.
• Google Blog Search: Google Blog Search is relatively new to the world of blog search engines and at the time of this writing is still in beta. Doesn't retrieve many results at this time and there are a lot of useability issues, but again, Google Blog Search is still just in beta. I'll update as they work some of these issues out.
• BlogPulse: BlogPulse is a dream of a blog search engine. Includes really cool BlogPulse user tools such as Trend Search and Conversation Tracker.
• Bloglines: Not only can you search the blogosphere with Bloglines blog search engine, you can also subscribe to site feeds and view all your feeds within Bloglines' feed reader. Here's my Bloglines subscriptions.
• Blogdigger: Blogdigger is a solid blog search engine that also gives you the option to search for local blogs, an option I immediately added to my bookmarks.
• Waypath: Waypath bills itself as a "blog discovery engine". This blog search engine features the ability to identify topic streams, which basically means that they pull out the meat of every subject post.
• Findory: Findory is a super-charged blog search engine. Findory not only finds blogs that you're interested in, but "brings you news articles from thousands of worldwide sources...and custom-builds a personalized newspaper for each reader." Very cool service; try building your own Findory page.
• PubSub:"PubSub is a matching service that instantly notifies you when new content is created that matches your subscription." PubSub searches blogs and is technically not a blog search engine, but since it does search blogs I included it here. Think of PubSub as breaking news alerts on steroids - it's an extremely powerful and convenient search service and once you start one, you'll wonder how you ever got along without it.
• Feedster: "17,268,315 feeds indexed and fully searchable." Feedster is a blog search engine with a twist: it searches and indexes anything with a feed, which covers a wide gamut.
