Senh: I've already been seeing some of that in action. I've noticed that the results I get when I'm logged-in are different from the results I get when I'm not. Sometimes, I get results from sites that I'm Plus One-ed on. Sometimes I get results from sites that I visit often, like MoviesWithButter.com, for instance.
Last Thursday, Google launched another algorithm change to their search engine that rewards “fresher” content. For example, if you’re searching for a current event, the latest news articles would pop up to the top of the page. 35% of the search results are affected. I was thinking this should be great for a news sites like Wopular. I checked Google Analytics on Thursday and instead of getting a traffic boost, I got the opposite - a dip.
Senh: This is a touchy area. I can see both sides of the argument. Google probably doesn't want to get involved with moderating reviews on Google Places, but they will have to because there's an uptick of unscrupulous businesses are going to their competitors' pages and writing fake negative reviews.
Senh: Google did get their start with Yahoo when the web directory used it as their third-party search engine. Yahoo is mainly a content company nowadays, but they're still the second largest search engine in the search market. Owning Yahoo and replacing Bing, which Yahoo currently uses for search, with their own search engine would make Google even more dominant in search. It's insurance against Bing (Microsoft). Expect a bidding war between Google and Microsoft.
Senh: It's interesting only because MC Hammer is involved. I doubt the site has any real potential, but if he focuses on entertainment, he might be able to carve out a niche. WireDoo is not the first search engine to show related topics to keyword searches: Bing already does it, and Ask did it before Bing. Still, when it launches, I'll check it out.
