Someone has been envious on the Vark acquisition :-)

Of course VC makes sense in their case. There is no barrier to entry in this field, the model is clear:

* users tend to type questions in search engines

* search engines tend to rank up exact matches (especially with some trivial SEO like put the question in the title and url)

* given the proper environment, users will help each other answering those questions for free, generating lots of content - exposing ever bigger surface to the search engines
