Since that post was made, summaries that are visible in the timeline were in fact added, though not stylized post content with images etc for long posts. So I think there have been some improvements (and I don’t fully agree with Havn’s characterization!).
That said, yeah, discovery is hard. There have been attempts with Discover and Recommendations, though I think they both kind of don’t get there.
If we shared more interests, I’d be sharing some blogs with you! Manu’s series, People and Blogs, is ending soon, but has lots of great interviews from people who have blogs, and all the interviews include like 5 recommendations and I’ve found it’s been a great way to discover new blogs.
