Matt Cutts is a good example of where reputation rank would work regarding Google, but that's a very simplistic case. What about information that is more art than science, more philisophical than factual? Would Richard Dawkins have a higher reputation on religious matters than the Archbishop of Canterbury?
Even something like the trust in reportage is very much in the eye of the beholder; one man's BBC is another man's Fox News.
I suppose my question is: who decides on the reputation? Twitter isn't all about technology and social media, despite how it may seem, and as the user-base expands this will become increasingly obvious. It might be nice if we were allowed to apply our own parameters about whose reputation we value.
1. Almost all links in tweets are in short form, wont this affect the indexing process?
2. Can twitter be expected to come out with such drastic and active steps when they haven't been able to come up with even a decent business model?
Just a counterview. I love the new idea behind Twitter search, personally :)
2) twitter is using bit.ly which they have a relationship with
3) it's expected that twitter will acquire bit.ly
4) business model, hell they can't get their core business working right, and you expect someone to pay for it ;-) lol.
the money is actually in the search, but I really do think they need to get the architecture to a point where it will scale before search is really something to worry about.
I can understand such outage if they are not so frequent, and they are not.
Twitter are stepping into the world of search and will have to produce an algorithm that is as complex as Googles in order to make it one thing and in a word that's "useful". It will fail whale totally if tweeple simply cannot find relevant results, simple as that.
To reply to Aditya Rao:

I cant remember Google having a business model in the early days either. Now that search is of such obvious importance, and all the differing revenue streams associated with it, Google effectively created their own business model, the main barrier was users.
Get the users and the model can be whatever compliments the service and attracts more users. I think Twitter are following the same line and Search is their business model!
Addressing Gmail being down. I dont care, its free, its up enough to be damn useful, and frankly I don't think I have a right to complain when someone has handed me a service like this, no ones perfect and s**t happens to the best of us. (but still, communication is key and a simple announcement to users would sort most of their problems out, I thought they would be more than aware of this.)
FriendFeed does a better job of adding value thought comments and likes, but they haven't been able to figure you how to capitalize on that yet.
First is to highly constrain the input side (i.e. ask structured questions and push content into categories from the start, and/or require independent verification of submitter credentials). We ( http://www.vanno.com/ ) use the former, while Wikipedia is a good example of someone using the latter). The advantage is that the noise is cut down from the start. The disadvantage is the user/submitter base is much smaller, and submitters have to do more "work".
The second approach is to try and infer user reputation (credibility) of unverified submitters from their unstructured activity stream. This is what Twitter has to do. It's a horrible signal to noise problem, made worse by the fact that the target is always moving - i.e. people will always try and game any system or reverse engineer any algorithm. The advantage of this approach, of course, is that you can get an enormous user base and activity stream quickly, and submitters don't have to think much before hitting the send button.
Our bet, for what it's worth, is that the user reputation backward inference problem will ultimately prove intractable for completely unstructured activity streams - i.e. the defense (prevent gaming) will be overwhelmed by the offense (people trying to game the system). What's going on with Digg's attempts to keep up with systematic and professional gaming of user "reputation" support this view.
We're betting on the structured input approach - i.e. suppress the noise from the start. We wish Twitter good luck, but bet that in the end they'll be forced to expand hashtags to more structured categories, and enforce some level of a priori submitter "certification".

Even the best system I can imagine (a second-by-second ranking of each tweet based on each person's independent assessment of the value of the tweet) would work against Twitter's central idea: a foundation of egalitarianism, the efforts of people to stand out from the noise, the efforts of people to pan-handle the noise for good information, and an element of luck.
Reputation with respect to some specific tweet is very much a contextual issue and what may have warranted high ranking even a moment ago may no longer warrant it now for a whole slew of reasons. I do no look forward to the day when my stream is overwhelmed by highly ranked tweets all saying the same thing because those "in the know" are only talking to each other. I could go to the dailies for that.
I think the best method for this assessment of the value of a tweet is the ever alert folks who are doing that right now and pan-handling the stream quite effectively. For example, if I know someone who should know something on some issue I seek out their tweets -- I don't need an algorithm to decide for me. A better search tool would help, but based on content not reputation.
This kind of search will turn Twitter quickly into the preferred search-engine for all "fresh" information – and maybe even make bookmark services redundant in the long run...
