Could potentially be integrated into NAS storage systems like openmediavault. Or as shared forum database storage.

Forum database could be problematic, IPFS is based on append-only logs similar to a blockchain, so there isn't actually a way to delete anything (let alone decide how you are going to delete an item from every peers copy of the DB). It gets worse, even if you had a clever way to do deletions, doing something like creating 50M posts and deleting them would still create 100M long chain of records just to store an empty DB, since you have to store the transaction records forever to build the models out of the logs. Just take a look at the ever increasing and unscalable size of a full bitcoin node that has to keep track of every transaction ever made just to store a current balance, and can literally take days to sync.

It makes sense for storing content addressable versions of software, but I don't see how this is a scalable way to build a p2p database for social media
