i realize for regular blogs and search its next to impossible - except to grab like the first letter of what ever comes in and alphabetize that..
really - it would need good databases - to make sure common things like all albums books words etc would work with it.
In a perfect world - you'd have a Search alphabet component - and get partners on board that had big databases in specialized categories.
so it might be words like: word(s) - powered by meriam webster,
movie(s) - powered by blockbuster, music - powered by cdnow .. etc.
the core idea is trying to put a new yet natural spin on search,, to me - i went.. i want this all in order, and i dont want irelivant listings for the most important one word categories - ie; moviews - i want every movie released - not bobs star trek fan
the other part is that you could theoretically have NO ads.. as the partners are ads ( sort of) and you make them pay you and make them provide results in very very simple googlesque form - ya grab a percent of any clicks as well - or sales
or what have you
- but there isnt a side bar of paid links..
i guess the hard part would be communicating to users what happens when you type:
basically alphabet bar would need to be designed to work on any one word input - so how do you communicate to use what words have been done..
* dont forget - you could search regular like now as well
*ps - googles ad sence relies on an outdated view of ads
all ads in the future will BE the content
just move on that front and you will win
