I often saw, that serveral websites put no-follow on some internal links.

For example:

Let´s take a submenu with articles:

Articles
- one (http://xyz.com/one.html - Linked without no-follow)
- two (http://xyz.com/two.html - Linked without no-follow)
- three (http://xyz.com/three.html - Linked without no-follow)
.
.
.

Now, there is a spot with new articles on the website:
Recent Articles:

One (http://xyz.com/one.html - Linked with no-follow)
Two (http://xyz.com/two.html - Linked with no-follow)

Should I always keep it that way?

Should every link to a site just appear one time visible to google? (i don´t mean duplicate content! Just duplicate links to the same page from different sections on the site!).

Could it be, that google perhaps don´t like it, to follow the same link to the same page over and over?


Thanks for any answers,
