Hey Hunter, thanks for the inquiry! Happy to help with this.
For this use case, if you're scraping the LI post to get the people who've interacted with it or mentioned the event, I've seen users have tools like Apify scraping those URLs on a regular basis and then auto-importing the date into Clay. Here's a video at Clay University about a similar use case.
Of course, if you have a different starting approach in mind, what does that starting point look like and what would be the next steps of the flow after it?
