Should I nofollow all my outbound links?

[izaiasalmeida]

I've read a lot of stuff and I can't get a good answer about this. Now I'm reading Wordpress 3 - Search Engine Optimization, and the writer says that less outbound dofollow links you have, better for you.

What is the best practice in this subject? Should I really nofollow more than 80% of all my outbound links?

Thank you.

Izaias,

You will get a bit of differing opinion, but I disagree with the author. First, it is believed that linking to authoritative sources is a plus for SEO. Second, you do not "lose" by linking to others. What he/she is likely referring to is if you have a PA of 30 and 4 internal links to other pages along with 8 to external, less would go internally than externally. 
To me, it makes no sense to worry about this as it is trivial compared to good content with quality outbound links that make sense for your audience. Then get links back to you, etc.

I would not worry about it and just leave them as do follow.
