Most blog links have indeed been reduced to just the name of the blog by default. Why? This makes the page easier to scan, and it permits extra emphasis for more noteworthy blog posts and articles. Roughly speaking, if a blog post hasn’t been linked by anyone, it’s unlikely to appear excerpted by default. But if a post does provoke some discussion, it may be featured as a headline on the page.
It’ll take some getting used to and will likely annoy many bloggers who use it primarily to get a list of who’s linking to what. Whether it’s easier to scan, only time will tell; I’ll have to relearn how to use it first.
The new design, though, does cure a lot of the problems that Gabe noted a few weeks ago. Most notably, having numerous threads for related articles–especially multiple variants of the same AP or NYT article–was indeed “lame.”
