5 Reasons: Social Bookmarking Sites are Useful for Bloggers

Yes, they are extremely good for basically 5 reasons:

1. Making into the homepage of Digg, Fark or Shoutwire can increase your traffic immensely for a day or too. It can also increase the number of subscribers to your feedburner.
2. The social bookmarking sites give you a lot of new ideas to blog about.
3. They increase your earning from Adsense and other sources slightly.
4. If your entries can make the homepages of Digg, Fark or Netscape (and any other social bookmaring site) then your confidence level can go very high just like your traffic.
5. If your blog entries get picked up by the social bookmarking sites regularly then you can become a star blogger sooner than you expected.
