I just did some a searches, using the following 3 phrases: 1) Pentax 2) Pentax cameras and 3) Pentax camera reviews.
I used Google and then Yahoo.
After going through the first five pages on each of the six searches, there was NO sign of RH's blog.
Perhaps your searches show his blog because you have visited his site?
When I do the search RH Pentax, I get a bunch of Pentax lens hoods.
I had to actually key in RiceHigh Pentax to find his blog.
What are the odds a person looking for reviews of Pentax cameras is going to key in RiceHigh?
And who is going to base a buying decision on some poorly phrased, sometimes difficult to understand technical jargon. (No offense RH. You speak English better than any of us speak Japanese).
Would you actually skip over DPreview and the other professionally done reviews and say to yourself : "Hmmmm... sounds like this guy RiceHigh is my kind of guy. I'll take his advice over those other uninformed sources."
