RSS is an effective way to keep a tab on the news, blogs etc. I've tried some tools such as RSSBandit initially and finally settled with Thunderbird. See how to use Thunderbird as an effective RSS tool, from here.
My reasons for using Thunderbird for RSS reading
1. In one window, I can read all. As Thunderbird is my mail client, I dont want open an another software for just reading blogs.
2. Power of Add-ons such as remove duplicates available in Thunderbird.
3. Easy to setup and manage.
4. It can download the blog contents rather than visting the blog to view the entire content. i.e. offline availblity.
Try it. Tell me how it works.
