Just a super quick question but since the Forem launch announcement (great job by the way) there have been pinned posts on the home feed.

Is there an event on I have dismissed the announcement for / missed by mistake?

They don't seem connected in any way and I couldn't see a pattern either (likes, subject matter etc.) so was just puzzled.

And if they aren't connected what are they pinned based on (and can I hide them if this is going to be a permanent thing)?
