Dynamically loaded DLLs are useful

Tell us what you think about dynamically loaded DLLs, as featured in this week’s Software Development e-newsletter. How do you prefer to load DLLs: for the linker to statically link the DLL into your application or to manually load the DLL with LoadLibrary or AfxLoadLibrary? Do you allow end users to extend your application? If so, how has that increased your application’s popularity?
