Is it really needed to place Nofollow attributes to Links?

[Prime Aque]

Matt Cutts has said in an interview (though am not quoting it here), that in his case, he wants to feel free to pass his site's PR juice to all the pages and outbound links he is linking with.

What does this mean to us? How does it affect us in dealing with the rel="nofollow" and the dofollow link attributes?

A short review: nofollow attributes will command search engines to ignore particular links within your content, it means Google and other search engines would not index these links. (although other search engines might treat nofollow differently.)

Is it really important or helpful to use nofollow? As of today, am still using it, however the bottom line about linking is "relevance". Links relevance can mean many thing to content writers and bloggers.

It tells us to link to contents that are:

1. trustworthy
2. informative
3. relevant to the topic we are talking

Note: there are informative topics out there, but somehow they do not connect with the subject we are talking about - why link to them?
