Relevance of articles

I want to discuss the relevance of published materials.
New article is read a maximum of 2-3 days. Then she goes very far into the archive and remains there unclaimed forever - in fact, the well-known problem of all sites of the blog type.

But the question is not about that. Today I have a problem with the update of the old article. I took additional photos to my previous material and decided to post them with comments in a separate article, because an old update would most likely go unnoticed. After that I received a comment in the comments that it’s not worth creating a new article, but it is better to update the old one. I deleted the new article, although many updates were approved.

It seems to me that in this case the value of the update is significantly reduced. There is no special incentive to update materials, if no one notices. Alternatively, it would be possible to shine a list of updated articles somewhere in the main tape.

What do you think? Maybe the question has already been discussed?
