It could be depending on what you're hosting. I'm sure some people would enjoy it better than bothering with social networks.
Social networks require registration. Some profiles are private and require approvals. On many social networks, users need to send friend request which require approval. Personal websites don't require registration and anyone can see it.
I think it depends on what your purposes are.
