Twitter is much more fast paced than Facebook (as said by DirtySocks). It all depends on who you follow, think about being near a fire and sending your pics to your local news station who is on Twitter. Pretty nice right?
Google+ and Facebook are competitors, Twitter has it's own league. They're two different types of social media, and Twitter is much more appealing.
Unless you're following a bunch of tweens who tweet about how "they just woke up with a hangover".
It all depends on who you follow.
I follow lots of people, no celebs. One of the people i follow is a big developer, and because of Twitter i was able to beta test a very popular app, how cool is that?
