But the internet may not be as democratic as they'd imagined, according to a study in the journal Communication Research.

And he analyzed the connections among the messages. Turns out that 50 percent of all replies were ___3___ just 2 percent of people who started threads, and who thus came to control the discussion. And the larger the newsgroup, the more ___4___ this effect became.
