I’ve noticed an issue with your blog’s RSS feed (https://huggingface.co/blog/feed.xml) that affects usability in some feed readers like Feedbin. Specifically, each <item> in the feed lacks a <link> element pointing to the original blog post.
Currently, your RSS items only contain a <guid> element with isPermaLink="true", which technically holds the correct URL. However, many feed readers rely on <link> to open the original post. Without it, they fail to provide a direct link to the article.
