150

"Robin Dunbar, a professor of evolutionary anthropology at Oxford University, developed a theory in the 1990s dubbed Dunbar's Number. The theory contends that the human brain is only capable of managing relationships--staying in contact at least once per year and knowing how friends relate to others--with about 150 people."

*looks at my LJ-profile* 175, 159 mutual. Well, minus some ghost accounts and journals that I read like newspapers and journals I actually don't read - it will be about 150, yes. And I agree it's the upper limit or very close to it.
