To be honest, it's cool if you relate to someone else who has the same problems in life as you do. I relate to these two: Spoiler: Here you go I'm not saying that the other vloggers out there are bad, but I like these two a lot. Both of them are funny, and I can relate to their problems.
If you generally like hearing teenagers complain about their lives, sure. For some it's nice to sympathise with others, but most of the time I see people making poor choices in life, so it irks me.
vloggers are fun cheap entertainment, really only enjoyable if they're done mby a personality you already like
I used to be quite into vloggers but it gets old. Natalie Tran is my favorite and really the only one I keep up with anymore. A lot of the others just don't seem genuine, like they're putting on an act, likely because they are. They're playing a personality. Obviously there are a few exceptions but part of the appeal of vlogs is that they're so real. I like Grace Helbig also.
