Like you, I also read most of the blogs from MSN Spaces, Blogger or Typepad.
It's often difficult to read by visiting my blogs regularly.
Google Reader simplifies this task of reading your favourite blogs.
Go to Google Reader and login using a Gmail account's Username and Password.
For example, to read my postings, all you need to do is to add the feed http://spaces.msn.com/members/thirumurugan/feed.rss to your Google Reader using 'Add Subscription'.
That's it, you will receive full text and notifications whenever I post new things to my Space.
And also, you can use 'Search for new Content' to find feeds on any topic.
