What is the problem that git submodules solve well? When should I use them? Or rather what is their use case?

The only use of submodules that I have seen 'in the wild' has been when used to share code between multiple repositories. From what I have experienced, submodules do not appear to be ideally suited to this use case. You run into git update submodule woes and your history gets filled with updating submodule pointer commits. If the 'sharing code' use case is not best solved by submodules, what problems are?
