Consider this gem from a recent post on TechCrunch:
As one of the commenter's rightly said, that is probably the most inaccurate description of Hadoop (or the Map-Reduce paradigm in general). The author, Erick Schonfeld, updated the post with another explanation based on feedback in the comments:
While this is better, it is still far from an accurate and concise description. For instance, I'm not sure I understand (for that matter, even Erick understands) the relevance/meaning of the phrase “it is mapping the data” in this context. Or that results are “combined into one big result” in the reduce phase.
Given the visibility and readership of a prominent blog like TC, I find such reporting to be below par. If the author had taken 5 minutes to just try to understand the basic map-reduce paradigm, all this confusion could have been easily avoided.

Yep, the quality of TC in general has dropped over the last two years since I’ve been reading it. I’ve come very close to dropping it from my daily reading list several times.
