Another thing on the "desert island" effect is that, from the perspective of a artistist or creator, it seems oddly difficult to get discovered on Twitter. Maybe it's something about the interface or recommendation system?
Twitter itself does not encourage creators who want to share content that much. I don't know if this is a problem with media integration (as mentioned in the article) or with the types of people who use Twitter, but as a creator of anything artistic it's not that nice of a platform. I've found tumblr to be much better, both in terms of community (lots of artists, game developers, musicians, etc hang out there) and in how the system itself works. People are much more liberal with notes and reblogs, which means it's easier to gain a following and it's also easier to get some data on how much something you created resonates with people.
