I’ll be honest, I’ll assume bad faith from Meta until proven otherwise.
A good example here is the first version of Google chat, which federated with jabber - until it didn’t. I was quite vocal about converting my friends to it because it was an easy entrance to jabber, with a brand and interface they trusted.
Then once it was big enough, jabber federation was cut off and we looked like the weird outsiders.
Federating Meta will feel like a win right up until it doesn’t.
That’s usually the case.
I live and work on London time. If I want to have a phonecall with someone in the Philippines, I have to be mindful that 9am for me is 5pm for them, so I’ll need to make the effort to start early to catch them while they’re still at work.
Without timezones: If I want to have a phonecall with someone in the Philippines, I have to be mindful that their working day is 1am to 9am, so I’ll need to make the effort to start early to catch them while they’re still at work.
I’ll still need to lookup when their working day is, I’ll still have to adjust/account for it, and I’ll still have to get up early / start work early to make that call. Getting rid of timezones doesn’t get rid of that +8 or the affects of that +8, it just renames how we communicate it.
