-User-generated content has the potential to achieve virality quickly. 
-Sometimes referred to as 'campaign' even. Some hashtags die, others become part of world history. 
-Typically user-generated viral content is... what? Pithy? Heartstring tugger?
-"Early responses" carry cultural weight that buys cultural capital, as evidenced by the "FIRST" or "INB4" internet trends. Cultural capital can translate to real capital for a retail or political enterprise, or more directly to an organization that seeks increased "views" on its ads.
-"Early response" can also create the impression of authenticity with the public, with later responses being more and more likely to invoke the suspicion of "bandwagonism".
-There is a psychological phenomenon of "social proof" (??? better one???), which in this case: an early, independent "endorsement" of a statement that has innate potential to catch a lot of eyes can stimulate the process of virality, or even possibly serve as the catalyst in that process.
-The ability to foresee the imminent virality of user-generated content in the social media space is therefore valuable.
-This model assumes that response/recognition is cheap, but missed opportunities are expensive. Therefore it aims to catch as many "peer-endorsement-potentials" as possible (true positives), even if it means mistakenly flagging others (false positives).

+Predicting early endorsement in user-generated content
+========
+
+Context
+---------
+
+User-generated content has the potential to achieve virality quickly, to the point where such content is even referred to as a 'campaign' - after it has already become one, that is. Some hashtags die, others become part of world history. 
+
+Consumers have become more savvy to the fabricated nature of many traditional forms of social proof, such as 'ambassador-style' brand advocates or "most popular" product sales. In the social media space in particular, one form of social proof retains an air of authenticity: the "early" response and/or endorsement. "Early" responses to content that has latent viral potential carry cultural weight that buys cultural capital, whereas later responses become more likely to invoke the suspicion of "bandwagonism". 
+
+Early endorsement of potentially viral user-generated content represents a brand "spending" attention on something that does not have an immediate obvious payback in terms of exposure (thus gaining perceived authenticity).
+
+Objective
+---------
+The ability to foresee the imminent virality of user-generated content in the social media space is therefore valuable. Additionally, latent viral potential and presence of early endorsements tend to correlate, with a synergistic effect.
+
+Therefore, this text classifier:
+* seeks to identify user-generated content likely to attract early endorsement, in order to "beat" the crowd and get "inb4" the bandwagon effect
+* specifically, classifies those top-level comments from a sub-forum that focuses on user-generated content, and that has a mechanism for giving public endorsement to comments (Reddit gold)
+* assumes that responding is relatively cheap, while missed opportunities are more expensive. Therefore it aims to catch as many "endorsement-potentials" as possible (true positives), even if it means mistakenly flagging others (false positives).
