You can’t do too much about the number of lurkers in a community. You might be able to shift the metric (participants / registered visitors) by a percentage point or two, but this comes at a crippling opportunity cost.
And that opportunity cost is to capture your current visitors. You should worry far less about lurkers and far more about visitors who never come back to your community at all.
