I don’t use my work email for private convos, just like I don’t use my junk email for coordinating group trips.
I addressed this in the final paragraph. It makes sense (to me, at least) to partition the communication medium based on the role or type of established relationship, but I don't think, e.g, that you use one account to talk to your friends from school and another to talk with your friends from the swimming club and another to send pictures to people you went camping last summer.
do you have gmail? well that says something about you. Hotmail? same thing
Hard disagree. What aspect of someone's identity can you infer seeing an email from joey@gmail.com? Can you tell their political values? Their religion? Where they were born? Their lifestyle? Marital status? Even if you were to take a jab at their gender, you'd be relying on the user part, not the domain. Saying you can know anything about someone by their email provider is no different than claiming to figuring out someone's personality by asking them their star sign.
which is choosing a topic (yourself) as the root of your identity
No. I don't have a personal domain because I want to talk about myself. I have a domain with my name because I want a stable presence and my name doesn't change, while my interests might. I don't like the idea of letting myself be defined by my interests.
Tying your identity to lemmy (or the fediverse even) is a losing proposition.
Here, we agree 100%.
You know what you’re getting when you go in (a programming forum),
Are you sure about that?
Anyway, I just wanted to say I am glad that p.d exists and happier still that is one of the topic-based instances that is thriving. I know that I am part of the minority opinion in this debate. If I have my way, soon we will have "ActivityPub Group Servers" where people will be able to setup, moderate and manage an actor without having to be in the same domain. Then it will be easier for people to find and decouple the "community" from the "instance" and perhaps more people will be interested in using the dozen topic-based instances that I created last year.
Oh, nice to see more topic-specific instances. Would you be interested in joining https://fediverser.network to add the instance and its communities to its database?
