Campus blogging for collaboration

If communication is a problem on campus--the right hand not knowing what the left is doing--would a blog help? My newest brainchild is creating a blog where people on campus could write about their ideas, plans, events, with the end result being that faculty/students/staff around campus might be able to lend resources or help with making an idea a reality. There might be possibilities for cross-campus collaboration that would not have been discovered through the normal route. But I'm wondering how to create a blog that people want to contribute to...one that is vibrant, lively, and used. Will need to research this!
