for services in which you don't want to run your own server, I'd rather it be serverless (P2P, like twister, or maybe like secure scuttlebutt) than having to depend on someone else's infrastructure.  if you're not going to keep your data to yourself, it's a lot better to have your account and data in a resilient distributed network than in a single node that's prone to fail and leave you out of service, more so if it's hard to migrate out of it once you started using the service
