> discoverability issues
Webrings[0] are somewhat being used again. I keep a list of the blogs I follow[1] in OPML & HTML, so that you can either bulk-subscribe, or browse through blogs that you might find relevant; you can do the same!
On RSS readers/organization, I didn't need a solution, because "personal blogs" post rarely enough that even following ~100 blogs, I see 3~5 updates per week.
