Dofollow blog – to be or not to be?

Friends, tell me please.
Dofollow blogs – they are relevant today?
Does make sense to do this blog dofollow?
How Google would react to that? (dofollow = increased the number of links from the blog).
The blog comments are the most significant way by which readers can interact with you or any bloggers. As I know, some years ago too much bloggers created doffolow blogs. But in 2015 it need or not? It can increase real visitors, but also increased the number of links from the blog.
Sure, I`ll dropping all generic comments like “Great article, it is very useful” or “Thanks for your nice article and efforts”. Will appruved comments from real peoples only. Will positive effect from dofollow blog in this case?
What you think? Will glad to any comments, also has been created poll for this question.
