Twitter as Search Engine

It's just always crossed in my mind, how does twitter could become a search engine?

A new media, a social network with a lot of post every single second give you more chance to keep updated with anything of information. Information given to you, without you realize, you already filtered it when you accept a follower requests on your account. I'd rather said it is an information, of course you don't wanna read someone who just ate a steak, or you just take a bath for two hours, something that really annoying. Basically, complaining is "the unrealized" habit haunting on everyone. That kind of complain was not count as information indeed.

Information is based on yourself, it's about what you need to know in the mean time. Let's say you need a brand new car, I am sure you will typed car, sell, cheap, or all of these words into google. What does google give you? sponsored links in the first row. But when you typed that keyword into twitter, it's all sort by the time you post these keyword. Meaning, it is more actual than what does google done. Last week I got to cover some activity in a book fair. I know the Title of the event already, I know exactly where the venue is, for reference I typed a keyword into search tab in Twitter. What I got ? , I got more information from who was there about an hour earlier. I know the pricing, how crowd the venue was, even which credit cards could give you more discount! Surely it helps.

But why that kind of search engine cannot beat google? my answer is, sometimes it will. The biggest problem is, all the post that come when you entered a keyword into, is not more reliable than google does. You even don't know who was the owner of an account that says "80 percent sale!" what if he lied? dissapointed. I'm just thinking, why could you post a hoax to be shared? If it's happen, what's the importance you use twitter? It's What’s happening? not What happen to you?
