GREAT question! I wouldn't say Netscape though as it was relatively short lived. I think Steemit is more like Google and will someday be a household name. We will hear people refer to posts they saw on Steemit instead of FakeBook. Others will try to get a piece of the social networking/blockchain pie, like Yahoo, Bing, etc. But they will never be used as frequently as "Google it" like Steemit will!
