Selena Gomez is clearly one of these people. The humble ones that don't see themselves as being above anyone or of a different societal 'class'.
I've been a "fan" of her music and tv and movie roles for years now. Going all the way back to Wizards of Waverly Place
I won't say that her Instagram post about her kidney transplant was brave because that would be cheapening it and just throwing out an insincere term. What she did, by directly putting what she's going through out there, makes her real. That she doesn't see herself as above her fans and others. In interviews she has been upfront about a lot of things. With this age of social media we seem to have this illusion that the amount of followers actually equates to having more/a lot of friends in real life too. It doesn't. Even Selena Gomez, despite her popular, has only a small group of friends (as she's said in interviews) that she's close with.
Social media, while great, is better when we limit our efforts of connections on it and only seek what's beneficial to us. Not in terms of connections but more about limiting the information we take in and not overwhelming ourselves with the bombardment. Her use of social media is social media done right though. She doesn't use it as a platform to post short blurbs and a photo. She actually writes and shares what's on her mind a lot of the time. Reaching out to people is how we should be using social media instead of talking @ people. Even if it's just one person that you feel you have many things in common with.
