How many posts should I pin?
What happens to something that you see all day every day? You tune it out, right? That happens with your pinned post, too. We recommend pinning in moderation, or not at all, to keep the feed fresh. Keeping the Feed fresh makes it more likely that members will see newly pinned posts, should you feel the need.
If you do pin a post, be sure to view it on mobile as well as the website to see how it looks. You don't want your members to have to scroll and scroll to get to the stuff they want to see, which is the items! :)
