Today also with Do Follow Links , No Follow links are also useful , Here I will give you the reason :
Nofollow links attributes do not allow search engine bots to follow link.That means if the website owner is linking back to you with nofollow attributes, it does not pass on link juice. Only Humans will be able to follow the links. Though some time back Google made it clear that they don’t consider nofollow link attributes but weightage of such links are really less. Even though, it’s a good practice to use Nofollow link attribute to those link, where you don’t want to pass link-juice.
