There are a few rss feed sharing/blogroll sites out there now but I liked how this one has a full feed for each list so you can see what each blogroll looks like in action instead of it just being a clunky list of individual links out to sites to click through. Plus you can follow other peoples lists through the site too.
Tbh I think there is a lot of room for improvement related qol and ease of browsing feed lists for sites like this and blogrolls in general but blogflock has been the one I've liked most so far after looking at a bunch over the years. Iirc I've seen people host their own blogrolls here and there with a visible feed similar to this site but I'm having a bit of trouble searching for the software they used.
