The first four have existed for years. I bet a lot of Tumblr users don't even know Yahoo owns Tumblr now. Yahoo search is probably getting more notice given now Yahoo search is Firefox's default search engine (at least that's the case in North America).
Yahoo has some great ideas like the Digest app and doing some great mobile and streaming products, but I don't use them, and I don't always hear my coworkers and my friends talking about Yahoo (well except my friends who are working for them, but they are still pretty quiet about what they are working on).
Maybe their Yahoo Original series will catch on some fire.
