In 2018 I ended up learning and doing a whole lot with my server:
I finally educated myself on DNS and moved all of my domains to my own, self-hosted nameservers.
I moved fully to my own mail servers implementing DKIM/SPF across all of my virtual domains.
Spun up my own mastodon instance and matrix-synapse server to move more of my communications to decentralized systems.
More to come in 2019.
