Tumblr is certainly growing in popularity. A recent Mashable article mentioned that according to ComScore, Tumblr scored 13.4 million unique visitors in the U.S. in July, increasing 218% from the same time last year. The “blog-meets-social-network service” is experiencing what most are calling explosive growth. Tumblr has been on my radar for quite sometime having witnessed how our teens use it and rave about it.
