I think Ben has hit the nail on the head here, churches take note:
Why do so many church websites look dated and stale?I reckon part of the problem is an over ambitious ideas about the kinds of content that will be available.
You build your site thinking 'wouldn't it be great to have a photo gallery'. It would, but if no one is taking a steady stream of good photos, then the gallery's most recent pics will be the ones you uploaded when you launched the site from the church camp back in 2006.
'Wouldn't it be nice for each staff member to have their own blog on our site' - certainly - but if they're not blogging now, why will suddenly start if you make a website with blogs?
