It feels like an appropriate time for one of those "state of the nation" posts that become necessary when accusations of a certain gravity have been made regarding this tired old web-site.  If memory serves, the last one was 
this article from January, 2009.
Such frank feedback is genuinely appreciated, as it keeps a man honest.  So, then...
In an exhange following notes on the 
2009 Xizihao "Daxueshan", a reader by the name of "Alex" made the following remark:
I am already pretty well stocked [...], so the cake from your friend at Nadacha isn't as appealing  as it might otherwise be. 
Also, your various glowing comments about  Nadacha smell like a shill.
Your  modesty is comendable, but like it or not, you are an arbiter of taste  when it comes to the world of online pu'er.  So, in the interest of  impartiality and in fairness to your considerably large and admiring  audience, I dare you to say something unambiguously negative about one  of Nadacha's offerings.  I bet you can't.
 
Of course, the reason for singling out this particular comment for special treatment is that it explicitly states the author's belief that I am happily "shilling" for Nadacha / Essence of Tea, and hence requires a more full and public response, as I'm sure you'll understand.
