I am on maybe a dozen Slack instances:

Multiple logins
Can’t follow users across servers
Paid version is $$$

Mastodon is easier/better than most of that even in the early days.

@dkiesow True. And running your own instance isn’t rocket science. There are implementations that work well even in a nimble raspberry pi, giving you full privacy for direct messages while still federating to reach out to the broader world.
@albertcardona Been wondering if it would run effectively on a Pi.

@[email protected] With a #raspberrypi running a #pleroma instance https://pleroma.social/ the service can run on your desk. See the README https://blog.soykaf.com/post/what-is-pleroma/

Qoto Mastodon
@albertcardona Been looking at Pleroma. Might consider a Pi instance at some point soon.
@dkiesow @albertcardona Can you run it on an old Lego mindstorms brain? I think we have one in the basement!
