I have just found a very useful webpage which focuses on staff development in regard to webquests. It contains different modules which deal with the various aspects of webquest design and webquests themselves. Click here to see this website!
The video below contains Bernie Dodge, the original creator of the notion of webquests, explaining in what ways blogs and wikis can be used in a webquest as well as briefly the features of each.
I have just found another excellent website that is in the form of a webquest building template. This would be really helpful for teachers when creating their own webquest because it goes through each step of the webquest building process in a very simple and teacher friendly manner.

Below is a sample of the what the website looks like.
