I tweet about everything, no limits for that, my followers can be from anywhere, and they are, I don't like tweeting about politics and religions, nor sexuality, nor poorness, just good and important things, because I´ve seen technology is making people simpler and they surely need some help in their lives.
Limitations - What the user will and will not tweet about.
I will tweet about beauty of life, advises for a better life, self-esteem raising, and maybe something else, but always important things
