are multi-site churches acting as 'all things to all people?'

Mark Driscoll says,

I'm looking forward to speaking about what we are learning at Mars Hill and focusing on what it means to follow Paul's command in 1 Corinthians 9:22–23, "I have become all things to all men so that by all possible means I might save some. I do all this for the sake of the gospel." Sadly, with the missional conversation often turning toward authentic community, the focus of using every possible means provided in culture for the gospel to reach as many people as possible is getting lost. It is as if the thought of thousands of people getting saved is a bad thing because it results in a megachurch without enough seats for all the people, as if the goal of ministry was to connect fewer people to Jesus. In saying this I am not defending megachurches in general, but am arguing that it is possible to be urban and evangelical, emerging and mega, authentic and video, evangelistic and reformed - because, in the missional world, "by all possible means" is to be taken literally.

What do you think?
