That's funny. The Verge (who have the same symbol as a logo) posed this: https://www.theverge.com/2016/6/4/11845466/what-is-the-deal-with-triangles

Also, the Washington Triangle (business district) uses this logo. It has been discussed in the past on here.

A triangle into another triangle has many connotaions:

1. A sign of knowledge
2. Illuminati symbolism
3. Norse mythology
4. Lazy hipster logo :P
