How is that a problem? Note that many design documents may not be the  
best thing to do since (I believe) the current implementation runs all  
view functions in a single design document in one go. So views that  
get called often should be put together with other high-call views.

Other than that, updating a view is a matter of updating a btree which  
is the same mechanism couchdb uses to store documents. If you have 30  
views and adding a document changes all 30 views then you'll have 30  
more writes on the view updates.
