Thank you for the observation. However, I have to point out that typing "Whetstone size" into a search engine will return the sizes for arbitrary whetstones.

Thank you for the observation. However, I have to point out that typing "Whetstone size" into a search engine will return the sizes for arbitrary whetstones. I was talking about the use case where a customer is on say Amazon and looking at a specific whetstone. Sometimes, the product descriptions are woefully inadequate. The vendor, in such cases, ends up being unaware of the inadequacy because (s)he has no way of learning what the customer is looking for. If a system such as Askite were to be embedded in each Amazon product page, customers would ask their questions right there, and at the very least, the vendor would come to know about the problem. So, Askite doesn't help in the discovery of a seller. It helps the seller convert a customer once the customer has found the seller.
