Show HN: Seven39, a social media app that is only open for 3 hours every evening

I think it's a really cool idea. I signed up because I had a brain fart and thought that "EST" was "European Standard Time" (I was of course thinking of CET).

So yeah, the current window wouldn't work for me, but that's fine. Everything doesn't have to be for everyone. We all live in our bubbles anyway; creating artificial rules could actually be ways of creating new, unexpected interactions.

This being said – if you were to adjust the rules to accommodate more people, I don't think it should be "open from 7:39 to 10:39 in whatever your local time zone is", because that feels like it would just destroy the whole idea – that everyone is there at the _same_ time. Also, it would still exclude people who work evenings.

An alternative solution would be to have multiple windows. For example, if you have one starting at 7:39 PM EST and another one at 7:39 AM EST, there would be more chances that there is some time during the day for people around the globe to check in. Depending, of course, on many things: time zones, sleep habits, work schedule, ability to briefly slack off during work, etc. It would remain true to the idea while opening up for some more people. Just a thought.

I also think each window could be smaller, maybe like just one hour?

I like the idea that something like this could be open for 3 hours in the evening local time. Like, you'd get totally different communities coming on at different times, and having completely separate experiences together. But some other people would bridge the gap.

While you're online, every hour some people would be forced to leave and some other people could join.

I can see the addicts rewinding their clocks already :)

are you a frontend engineer? cause I'd hope the time checking happens on the server ;-)

Where is the server getting information about the user's timezone from pray tell?

It doesn't matter if it's being checked on the client or the server. If the user controls what your code sees, they can fake it.

It doesn't matter if they fake it. They're only getting one window per 24 hours.
