Not for an unbelievable number of people (according to my own anecdata.) There exist large numbers (extrapolating from aforementioned anecdata) of people who don't know you can just visit a website - they think it must first be "googled." I've witnessed on a single occasion an individual who accidentally went directly to facebook.com, didn't trust that they'd gotten facebook.com, proceeded to Google, entered 'facebook.com' in the search box, then selected the site from the search results.
I suspect (intuition via anecdata...) that much of the Pinterest's target audience has similar levels of technical awareness and ability.
