My point is "what's the value added with this article?" is it - ease of explanation? - numerical example? - code?

I can find plenty of blog posts which do a better job at all these criteria with a simple google search.

I don't see any value added with this post.

Maybe the author wrote it to teach whatever he has learnt, but it's not worthy of HN front page.

There are already plenty of blog posts explaining the same topic (eg : 2013 post - https://janav.wordpress.com/2013/10/27/tf-idf-and-cosine-sim...). I don't know why people have the urge to write a blog post about simple things. I don't think there is anything new in the post that I can not find already.

This is just stupid, people writing about stuff that has been there for some time as if it is new. I Can't believe this link is there on the front page of HN. Sorry if it seemed harsh, but somebody had to say it.
