I think it would be valuable to give you some additional perspective on the pizza post, as quoted above. I do not say this to denigrate you in any way, rather I think it might help to understand what occurred
Added to the fact that this was the posters very first post here ever was the fact that he was posting about arguably the very best pizzeria in the country, or at least one of the top 5, as viewed by many experts on the matter.
Add to this fact that the poster also signed up for an account on Chowhound specifically to make this exact same post there (http://www.chowhound.com/topics/238334), in a thread that was 4 years old, one that a newbie (and I mean no offense here, it takes time to learn how to navigate around, especially on Chowhound) would not have easily found. Note the "yeah right" and "about gave me heart failure" responses there.
Add to that the fact that the poster has never bothered to post again
With all that said, the post had the strong appearance of someone who was trying to stir up a bit of a panic among pizza fans, roadfooders and chowhounds alike. For all i know, he posted on sliceny and/or other sites as well.
All in all, a little too much going on here for this to have been a true newbie simply concerned about a random pizza place he liked and missed.
All of the above – imho. Others may well disagree.
