RSS Subscription service Changes the rules of the portal game

Rss

Google's personalized homepage has recently been found to include support for RSS subscriptions:

The first 2 days I heard that the content of Bloglines is equivalent to 1/4 of Google Index, checked yesterday: the exact saying is June: Bloglines The number of articles reached 5 billion , the current Google index of about 8 billion.

0.5:8 = 1:16

Although a variety of search engine billions of web pages accounted for less than 5% of the content of the entire internet, but compared to a search engine: the content of the 500 million RSS feed is relatively high quality of a batch of data sources. So it makes sense to say that Bloglines's index is 1/4 of Google's (the most important 1/4).

Comments:

Bloglines how many RSS feeds:grassland The current number of RSS feeds is 3,000, the article number is 300,000, according to this ratio: Bloglines on the number of feeds should be in millions (Webleon : The number of feeds for Bloglines is 2.48 million).

RSS Subscription service does change the original rules of the portal competition: the rich source of personalized data sources to overcome the original personalized service lack of "personalized content" shortcomings.

If a portal knows the user's search keywords, know the user's preferences for subscription content, know the user's most recent click Preferences, the user behavior of the in-depth data mining is feasible, and targeted advertising has become more effective.

Maybe that day add to my Google will also be like subscribe with BlogLines Add to my y! As overwhelming.
