Yeah I guess I can take negative criticism :)
People like you may never understand this but not liking your Signature does not mean let down feeling. You simply dont like something and you want to change it. In case of Signatures we come into picture.
We do have > 5000 customers not all paying customers but yes hundreds of customers who have paid us.
We used to run a free services for the first 3 months and because of our mention in CNBC India we got thousands of visits in couple of nights. We stopped shipping free after that and started charging for the Signatures.
In graphology we toss lot of specific personal traits which does not qualify in the broad spectrum. I can send you one sample analysis if you want.
