Now, there exists one service which provides you with single link in order to subscribe feeds for multiple feed-readers. For example, you might have been using multiple feed readers and every time you go for subscribing feeds, you need to subscribe single feed multiple times for readers. But now, with single click, you can subscribe a feed for multiple readers through AddThis.
For web-masters, it is bigger relief that instead of providing feed/bookmarking buttons for number of websites like digg, del.icio.us, netscape, Furl (Bookmarks), Bloglines, Google Reader, MSN Alerts, MyYahoo, NewsGator, Netvibes (Feed Readers), they have to provide single link for bookmarking and single link for feedreaders.
AddThis provides you facility to add small, sleek and sexy buttons to include on your websites/blogs instead of adding number of links to different bookmarking/feed reader websites. Also, now you can track your website/blog stats as AddThis has partenered with HitLink.com which happens to be a simple website statistics tracking service established in 1999. It provides simple to use scripts to track the website.

I am liking the sleek buttons just added by AddThis.

Web Surfers! AddThis helps you collect information online with a single click, and send it to your favorite bookmarking service, feed reader, shopping service, podcast service, etc.
I also added a button for bookmarking in left sidebar as well as for each post which looks like –
