No, it looks like every few days they pick their showcase list and that list is attached to all their articles that get published for the next few days. Being a news site, the number of articles every day is quite large.
The list itself is hand picked. Not all my articles get picked and they seem to pick only the ones that might play well with their audience (based on subject matter, headline, what is topical, etc)
