Klout, the social media service that let social media influencers get free stuff is inevitably shutting down on May 25th.

While many of you may be confused that Klout is even a thing, you another 15 days to see who is influential in different topics and what your actual online Klout score is by going here.

Klout was acquired by Lithium Technologies for a reported $200 million.

“The Klout acquisition provided Lithium with valuable artificial intelligence (AI) and machine learning capabilities but Klout as a standalone service is not aligned with our long-term strategy,” CEO Pete Hess wrote in a short note.

RIP Klout.
