if you're not a popular figure, nobody ain't gonna tip shit :p
In my opinion, it's more about the content created than if one is a popular figure or not, and what you must understand is that these popular figures only become famous cause of what they have posted over time and thus they deserve to get tipped if possible.
Twitter launched a tipping feature using bitcoin. Could the social media platform now become one of the world’s best remitting experiences?
It's somewhat early to conclude on that, and it would definitely have it's pros and cons, but what's exciting about the news for me is that Bitcoin is being used for this and it is in the news for a positive cause, it is definitely going to be good for the network in one way or another.
