Thanks for getting back so quickly. That makes sense to me – no worries, and glad you approve of the rest of the article. However, I'm wondering if you're aware of the fact that there are some stringent policies about conflicts of interest on Wikipedia, to ensure that articles reflect a neutral point of view. You might like to read through Wikipedia:Conflict of interest, which gives you a run-down of this whole area. The aim is to try to maintain the encyclopaedic nature of Wikipedia, and ensure it doesn't get used for advertising or biased opinions.

The reason I asked about a reference was because of the policy outlined in Wikipedia:Biographies of living persons – there are no particular problems with your statement about the book in this article, but in general all statements in articles about living people need to be verifiable via citations to reliable published sources. This protects people like you from unfounded statements and rumours that could otherwise appear in your article (since everyone can edit Wikipedia).

By the way, did you realise that over 70 Wikipedia articles link to the Ross Piper page? See the list here. Best wishes,
