The update also sees a big revamp to Notes that makes it much easier to see the content you actually care about. No longer will you see endless likes and reblogs clutter the page -- they're reduced to a single line, and you'll only see the conversations. In other words, the Notes section now behaves more like the comments section on many of the social sites you visit.

Tumblr had promised that Replies would return, but they likely couldn't come soon enough. Yahoo bought Tumblr with dreams of becoming a major player in the social world, but it didn't pan out as expected. The company needs to do whatever it can to not only keep existing users, but draw in people who'd otherwise be happy sticking to Facebook or Twitter. Giving them a more familiar (if not completely original) experience may be the key to making that happen.
