Blog Title

More than once I have come across the fact that, while making a bookmark (in a browser) on an article from someone’s personal or corporate blog, I have to first copy the title from the text, and then paste it into the bookmark manager. Because in such articles, unlike articles from thematic feeds, only the name of the blog and the name of the site are indicated.

Why not add there the title of the article?
(this is about the title tag)

But I suppose that this was done intentionally so that such articles would not be used by the authors for SEO promotion of their personal sites.
I understand that. Only surprised that in this context, personal blogs and paid corporate blogs are on the same level.
