This is TumbleOn’s “Explore” view. Explore view shows you 4 or 5 pictures from a photo stream (including your dashboard, your likes, and more). You can simply tap on a photo stream to start viewing it.
The Explore view has 7 sections, “My Stuff” for your dashboard/likes/blogs, “Bookmarks” shows previews of the blogs you’ve bookmarked, history shows previews from blogs you’ve viewed, “Following”, “Followers” and “Our Picks” shows blogs we recommend. The most exciting section we added was “Analyze”. If there is a blog you like, you can analyze the blog to find out who they reblog from. Let’s just say this opens up a ton of new Tumblr blogs you might like. We are personally pretty addicted to this feature.
