Usage of Shared

[Colden Cullen]

Hi all,

I've been trying to learn more about how the shared qualifier 
works, and so far I haven't been able to find much. I've read the 
"Migrating to Shared" article, as well as the shared section in 
"Attributes", but neither really give a good explanation on the 
details of what should be shared and what shouldn't. If anyone 
has any resources that they can share to help me (and others in 
the future) understand how and when to use shared it would be 
greatly appreciated.

Thanks for the help!
