I don’t see why beauty would improve the quality of Instagram posts, other than for people in the beauty business. For friends following friends (which I assume is the majority of users, I don’t follow a single person I don’t know personally and that doesn’t also follow me) beauty and glamour isn’t really important. I just post pix of holidays and kids to keep family up to date and entertain my friends. Yes I’m neither young, rich or beautiful.

For thoughts in text I think twitter is a better platform than fb.
