There are two fundamentals of a blog, one is that it is a web page and the other is that the page includes links. A linkblog is a special form of blog the soul purpose of which is the sharing of links to other web pages and therefore contains only the titles of the source pages and a link to them and no real commentary related to the links. All blogs contain links but usually include commentary, hopefully in the voice of a human author. Because the purpose of linkblogs is sharing and the purpose of RSS is sharing, the alignment and perhaps even the dependency of one on the other is natural, but the RSS feed is only useful with a RSS feed reader whereas the linkblog is useful in every web browser. In some ways the focus on the RSS feed is anti web. Mastodon, Bluesky, and other timelines are conceptually RSS feed readers but I do not think they are the web.
