They're tumbling one at a time to the Great Gooliath. It won't be long before the others follow.
Google will, or I should say, is the World's repository for information. They are the Gorg. Within the Gorg will reside those such as Ask and whoever else gets assimilated in the near future, possibly Yahoo! Bill would never give in to the Gorg so Live would just cease to exist, an oxymoron so to say. The Gorg is growing quickly. "Google is search". Who can compete with Google now? Who? I don't mean to sound like the Google Cheerleading Squad but I'm more of a realist and the truth of the matter is, all of the above is true. :)
Hey, if that is where search is heading, I don't have any problem with that. As long as the ReGoorgitations serve a different sets of results, that works for me. I'd really like to see an SE that serves results randomly based on the first 50. :)
I don't think it is that gloomy yet for Yahoo! and Live. But, with the 4th player now joining forces with Google, or so the rumor says, that gives Google a few more percent of market share. At this point, neither Yahoo! or Live can afford to lose a "few" more percent to Google.
