And out come the knives for Google’s forthcoming search changes that push Google+.

The only words you really need to know in the statement below emailed to me by Twitter: “We’re concerned”…

For years, people have relied on Google to deliver the most relevant results anytime they wanted to find something on the Internet. 

Often, they want to know more about world events and breaking news. Twitter has emerged as a vital source of this real-time information, with more than 100 million users sending 250 million Tweets every day on virtually every topic. As we’ve seen time and time again, news breaks first on Twitter; as a result, Twitter accounts and Tweets are often the most relevant results.

We’re concerned that as a result of Google’s changes, finding this information will be much harder for everyone. We think that’s bad for people, publishers, news organizations and Twitter users.

We’ll see if Facebook responds as well. I’m sure they’re having the disucssion right now as to whether they should ignore this or take their shot. The problem they have is the relationship with Microsoft for Bing social search — but that’s different, it’s an agreement between two independent companies (though Microsoft owns a small share of Facebook via the investment a few years back).

Microsoft is likely in a similar boat. They probably want to say something but they have to think about their Facebook deal — and they have a Twitter deal too. Yahoo may respond, but will anyone really care? I’m sorry, but it’s true.

Meanwhile, look for a Google response to the Twitter response to the Google move…

Update: Sure enough, here’s Google’s response.
