The great thing is both ideas aren’t mutually exclusive, so both could be supported, giving developers flexibility of the model they’d like to support
The reason I suggested the “developer push” model is that the current API is fairly close to supporting it. You could do “developer push” with the webhook version as well: if Tidbyt offers the option of triggering a pull, then you can use Tidbyt for time-sensitive updates.
I’m interested in the breaking news, someone just went live, real time notification possibilities of Tidbyt and would be disappointed if there’s no possibility to say “I want to show this up now” type notification (as I type this, there is a feature request in the suggested topics for PagerDuty notifications, which would likely require this type of usecase)
