Why don't I see all the items I posted at the top of the feed?

When you post multiple items, the first 5 items go right to the top of the feed but the rest of them are posted lower down at first and get automatically bumped up to the top within a few hours. This helps make sure that one person's items don't take up the whole feed all to once.

Keep in mind, all your items will eventually get bumped to the top of the feed automatically.
