What? Twitter's selling point was how simple and intuitive it was.
> It seems like one must be a celebrity, CEO, or super fan to use Twitter at all.
That's because Twitter changed from a "user" focused to a "celebrity/journalist/CEO/etc" focused platform.
If seems like you got introduced to twitter in the past 2 or 3 years. Twitter was nothing like it is now. You are describing what twitter was 5 or 10 years ago. I don't think twitter is going back towards a "user" oriented site. The same with youtube, instagram, etc.
