Well I thought about it and if it's a body part there will be someone into that. Then I thought maybe poke, nope some are into that too. I guess maybe "status" port? Kindof like having an away message. It could be a fixed buffer as to not overlflow. Of course that could be accomplished in DNS using TXT.

Honestly I am too lazy to make an RFC. Maybe if enough people make a finger.domain.tld text record it would catch on. [1]

    dig +short -t txt finger.nochan.net
    "status: currently spending time on hacker news."
