"a following" is just one type of asset. Ben Newhouse, who I didn't mention in my post leveraged his asset of building Yelp Monocle (as an intern!) into Bubbli (http://bubbli.co/intro/). It's undoubtably true that Bubbli could not have been built though, without leveraging Ben's asset. A different startup could have been built that might look vaguely similar from the outside but it wouldn't have been Bubbli.
