Google Reader has a module that can be added to Google Personalized Homepage (/ig). You can view the posts from your favorite blogs in one place, without adding a separate module for each one. Posts open in a bubble and that is handy if you want to see skim the posts. You can change the number of posts shown, how they are opened (in a new window, in the same window or in a bubble).
Google Reader and Personalized Homepage are somehow similar: both allows you to read feeds, but the reader lets you tag feeds, rate posts and catch up with the news faster. Google could also integrate Google Reader into Gmail, like Yahoo did with Yahoo Mail Beta.
