#Mobile is where the growth is in #startups, venture capital portolios, and user activity, according to a post by Fred Wilson, the managing partner at venture capital firm Union Square Ventures and a frequent blogger.
But one of the problems is that third-party reporting services such as comScore, Quantcast, and Alexa are showing flat user growth in the first half of the year, mainly because they aren’t capturing web usage that is “growing like a weed,” Wilson said. He wants a service that measures audiences across mobile and the web. New York-based Wilson is recognized as a leading voice in venture capital circles and he has made some high-profile investments in startups such as Twitter, Tumblr, Foursquare and Zynga.
