I lead VentureBeat’s coverage on social media news, but also cover news and industry trends in e-commerce and mobile.

Previously, I was a senior reporter at Mashable. I also have experience in broadcast television and introduced social media reporting to the NBC San Diego newsroom.

I hold a Bachelor of Arts in English from UCLA.

You can find me pretty much anywhere on the web under the handle “jbruin.” I often tweet, instagram, facebook, and path on tech and the world at large. Sometimes I get a little NSFW on these channels, so consider yourself warned.

I also abide by VentureBeat’s Ethics Statement. I don’t hold stock in any company that I cover and I don’t accept gifts of any kind for coverage (though I do possess some startup swag collected from parties and such over the years). On occasion, companies send me samples and test products, but I disclose these details in stories whenever applicable. I do have a Bruin-bred bias against USC, a fact that causes more conflict in my personal life than it does in my reporting.
