Discussion
Can you tell us more about how you think it should work? I bet a bunch of people would be happy to give feedback and share ideas early
I'm building a service around it but it's nothing complicated. It's just an ETL job on a schedule with a checkpointing algorithm.
I'm tackling from the perspective of creating an aggregated feed of items the user wants from around the Internet that they can follow. Less so posting as the user themselves from other personas from around the Internet. But that may be a future enhancement.
