What's topic drift?

  It seems to be a specialized term referring to the change in focus of blogs [0] and online communities [1] over time. This strikes me as a very specialized concept, rather than a generally-important term in machine learning as a whole. Edit: To add my perspective, with years of industry experience and graduate-level machine learning coursework, I have never before encountered this term.

    Also seems closely related to the concept of stationarity in time series analysis [https://en.wikipedia.org/wiki/Stationary_process https://en.wikipedia.org/wiki/Stationary_process]
