Sorry, but I do think it's snotty. To me, Frostfell came across like, "Well, how could you NOT know who I am and who my mentors are?"
Seriously. I have no idea who she/he is and who their dogs are and who their mentors are. That's ridiculous. How am I supposed to know what he/she has experience in?
So yeah, I'm absolutely going to check with the people I know face to face, who have been my personal mentors for years over someone with a pitbull in their avatar who may know nothing.
Internet advice is just that, internet advice. Which I didn't ask for in the first place.
Had I said, "Wow, what should I do here?" Then yes, please give me that Solicited advice. But, I didn't ask. I asked for a recipe, not advice on how to feed my dog.
So, if he/she didn't mean to come across as being snotty, then that's cool with me. Intent is all well and good, but it's perception that's key.
