Weblogs and Webquests

I think both a weblog and web quest are both useful in the classroom.  Weblogs are a good way of  finding and sharing information.  Web quests are a great way of assigning lessons that require students to utilize technology, while at the same time monitoring and dictating which websites they visit.  I just completed my first weblog and web quest.  I think both are useful for the classroom, but I thought creating the weblog was easier.  I also think a weblog can be used to cover broader topics while the web quest represents a more specific assignment.   What do you think?
