Should I rewrite my links into aliases? Is it of any advantage, in addition to using Global Redirect, to rewrite html links from /node/nid to /article/this-is-the-title, even though in both cases traffic is directed to /article/this-is-the-title (by Global Redirect).

Edit:

From this answer I gather that I should use Global Redirect so that aliases wouldn't cause "duplicate" content.

The same answer suggests a way to intercept links, passing them through functions to "convert from node/nid to article/title". However, I am green at coding Drupal, and have no clue as to go about it. Could some one advise on alternatives? Or ways of making this less cumbersome?

I am also adding this link to a related answer on avoiding disadvantages of 'same content/multiple URLs' for whoever's reference.

The same answer suggests using the l() function to have Drupal use "pretty paths" automatically.
