Just found Roogle (thanks Robert). Looks interesting.

Well, it not so hard to get idea of  "RSS Google", and when we mix all day snowing, nasty Windows crash and little dose of frustration then man is capable of everything. But seriously, it's great and really promising work for now (now index more than 10000 RSS newsfeeds and growing), and I definitely will watch for future development of this. Just subscribed for The Roogle Blog. Just hope that Scott (Johnson) will add also RSS feeds from DotNetWeblogs.com weblogs. Hey Scott, if you read this, OPML is accessible from DotNetWeblogs.com main page.

Maybe sounds like overstate a little, but it looks like that something new is emerging. RSS newsfeeds are different from HTML-based web pages. News Aggregators are different apps comparing to web browser, with different possibilities and different patterns of use. Apparently (I saw this on myself, too) use of newsfeeds aggregator apps change (or at least start changing) way how we gathering content (not only news) from web. 

Personally I think that RSS format isn't just for publising info about changes on some website (although for now I do not heard of web site that provide just RSS newsfeed without HTML-based equivalent for browsing via browser, but in future who know). As I wrote on last Friday in my weblog post Changes started or few thoughts on RSS emergence RSS, imho, contain much more potential. And while looking on projects like Organica or Roogle it seems that I am not only one who thinks so.

UPDATE:

It seems that DotNetWeblogs.com RSS newsfeeds are already indexed on Roogle.
