Nowhere on the page does it say "exploding", OP is exaggerating what is roughly linear growth. I think the title should be edited.

Edit: To be clear, I'm not saying this is not worth posting or should be taken down, just "exploding" does not even remotely describe DDG's traffic. The post was interesting, only OP's fabricated title is inaccurate.

Edit 2: Several comments mention the graph does show daily searches, and is therefore showing exponential growth. My reason for thinking it's cumulative and not daily, is because it says below that the daily record is 29 million searches and that the cumulative number is 22.569 billion. When hovering over the last value in the graph, it shows 22.2 billion.

For the record, the current title is "DuckDuckGo Usage is exploding right now".
