I was just reading, in a writeup about "wiki", that there's a 90-9-1 pattern, where 90 percent of members "lurk", 9 percent speak up occasionally, and 1 percent are regular contributors. There are apparently ways of improving the ratio, but the overall pattern fits with a lot of human group endeavors.
Consider that posting your words on the Internet is a form of public speaking, and then consider the statistics on fear of public speaking.
Might be worth considering ways of encouraging the quiet folks. I myself have been absent for months now, not even lurking.
