This is my startup - TechCrunch took the UK pop-culture spin on the article, but I was very pleased for the coverage!

Our product is quite niche and B2B, though very much has a technology and internet focus. Ask away with any questions.

Interesting. Is the content automated or professionally added?

Bit of both - the sources are "curated" and then we automatically discover other sources. A big part of what the software does is to establish source quality and authority.

The taxonomy automatically evolves - so for example during Halloween, words related to Halloween rise into the statistics even though we never manually seeded those words into our system.

How do you measure the sentiment of opinion ?

The paper describing it is well over 7000 words(!), but basically through natural language processing and machine learning.
