1. A non-transitory computer-readable medium embodying a program that, when executed by at least one computing device, causes the at least one computing device to at least: retrieve a first text block from a network site, wherein the first text block corresponds to a user, and the network site includes user generated content; track a retrieval status for the first text block, wherein the retrieval status comprises a time of retrieval; employ a text classifier for generating a score for the first text block, wherein the text classifier is configured to be trained by feedback for determining that a content of the first text block expresses an actionable user concern capable of being addressed by a customer service agent; determine that the content of the first text block expresses the actionable user concern based at least in part on the score satisfying a threshold value; in response to determining that the content of the first text block expresses the actionable user concern, associate the first text block with a queue; and determine that a second text block has been retrieved from the network site.
2. The non-transitory computer-readable medium of claim 1 , wherein the program further causes the at least one computing device to at least employ a set of application programming interface functions.
