With Tumblr speculation swirling, Yahoo (YHOO -0.3%) has scheduled a Monday evening NYC press event; CNBC reports Marissa Mayer will speak. Wells Fargo gives an overview of Tumblr's opportunities/risks. The firm notes comScore estimates Tumblr had 115M PC unique visitors in April (+85% Y/Y) and 14.5M mobile visitors (+227%), that engagement is strong, and that Tumblr is targeting $100M+ in 2013 revenue following just $13M in 2012 (ad sales are only starting to ramp). Wells thinks Yahoo could monetize Tumblr the way it did Flickr, but also points out the site has a ton of "provocative and even salacious material" that could deter brands.
