Thanks for your feedback. The number next to each post title is the number of tweets referring to a particular job post. On recent tab, most of them are '1' as they are the first occurrence, however on popular tab (7 days/30 days), you can see the count as the number of tweets referring to that job, which implies popularity of the referred job post.
