Must a church have a website?

I received a solicitation today from one of the big Christian publishing houses that said "80% of your visitors will find you on the web." They wanted to sell us some web site design and hosting services. Our church doesn't have a website. I'm very new to this blogging thing. Does this count?
I know that keeping up a website is another whole round of activity that small churches may or may not be able to afford. What if we spent our time actually talking with people, listening and interacting with flesh and blood?
Do churches absolutely need a website in today's culture? What if we really wanted to tell people about Jesus in person? Doesn't the anonymity of virtual space make people even more lonely? I'm not sure that the answer is clear.
The brand new moderator of the Presbyterian Church USA--Bruce Reyes-Chow--is a web-sophisticate. He uses the multi-channel communications of web 2.0 with ease and abandon. [See his blog at right.] One of the reasons he was chosen by our branch of the church, I'm guessing--I wasn't there, was that he can communicate so well in a variety of media. I suppose when Jesus comes again, there will be something like an absolute explosion of communication, or maybe community. Then we will know face-to-face and perhaps this will all be moot.
The unique message of Christianity is that God so loved the world that God communicated IN PERSON. Ours is an embodied faith. Jesus is human AND divine. I still think there's something to be said for eye-to-eye, stand-facing, mouth-grinning, heart-to-heart conveying of the good news.

If you have an opinion about this, I'd like to hear it.
