Kevin Rose, founder of Digg, co-founder of Revision3 and Pownce, as well as investor in Twitter, has just published his 10 tips to get more followers on Twitter. With over 1,167,000 followers, he is the most followed user after Barack Obama.

Here is his advice:

1. Explain to your followers what retweeting is and encourage them to retweet your links.

This will allow you to promote your @username in social networks, which will give you even more clicks. In fact, you can even follow your own retweets using the retweetist software.

2. Fill out your bio.

The "bio" allows people that do not know you to learn a little about you. This field is also posted on the "suggested users" Twitter page. A blank or non-pertinent bio discourages people from following you.

3. Post links to your Twitter. Everywhere!

Post links to your Twitter profile on Digg, LinkedIn, Facebook, your blog, in your email signature and all you other online spaces. There is also a TwitterCounter button (much like a FeedBurner) for your blog.

4. Tweet about your passions in life and #hash tag them
