It's a change @saipetch made. We're updating the "posted in" section to work like licensed video swap does, where you hover over the "..." and a tooltip pops up with a list of all the articles a video is posted in. The special videos implementation of that will be done in https://wikia-inc.atlassian.net/browse/VID-1601. For now we're just using a css overflow: ellipses to truncate the list. As for the high number, we discussed it when building LVS and it seemed reasonable.
