I think MongoDB has a place, but that place isn't being the database for a big distributed content store for a web site or something like that. Where I do think it has a place is for some of the in-memory data structures of a node running an application or a service. Applications tend to have a lot of data in various structures that it works with while it's running. Sometimes you need this to be persistent and sometimes you need to be able to scale this across a node. MongoDB is fine for this, so I think of it more like a SQLite replacement.
