Blog search!

So here we have finally an utility to search blogs. Well my first reaction was whats new in that? I mean you can always do a google search like 'search key site:blogspot.com'. And you may search all the pages (almost all) present on blogsphere. And same may be done with 360 and others. Then I thought maybe they have just done this and added links for the same eveywhere.
But then reading a bit more into the things, I soon understood that what Google is trying to do here is awesome. They are not just searching the pages but doing it in realtime. They are indexing these pages almost instantaneously. One may ask what's big in that ?
Well first for the people who don't know about this, Google indexes all the webpages that have been updated all over the world twice a month (it's called Google dance or something) and it visits all the webservers all over the world and collects all the information. Thats why those webpage contents that have been recently updated are not present on Google.
Now the question arises, what's the need for realtime search of blogsphere ? Well for the starters we may say that blogs are updated much more frequently than webpages and it's better to index them in realtime, so that all the blog content is searchable immideately.
But is there something more to it ?
There maybe! I have for long have this feeling that there is more to blog than just being amusing, informative and personal. Blogs may easily kill journalism as we know it, in this century. Already almost all important geek world information comes from blog. There are blogs by developers, managers, companies which gives much needed insight into the tech world, which is generally ignored by mainstream journalism. Apart from tech blogs there are blogs from all walks of life like cookery, psychology, economics, finance and what not. In my view blogging will change the way we look at news today. Google armed with deep personal insights of a person maybe able to come up with news and information that one actually wants to read.
I know I maybe just reading a hell lot more into it than what it is supposed to mean but still there is a possiblity that we may eventually find out what Google actually is!
