I think there is another phenomenon going on with Facebook migration because the posts there are not anonymous. You know who you are talking to, and others know they are talking to you. This results in more careful posting, I think, because people can and do hold each other to a bit more accountability--for example, if someone says they won this trial or that, others will more readily know whether or not this is true. In addition, when everyone uses their real names, it is a little easier to assess the experience level of those giving advice (and those asking for it as well), which results in fewer instances of those with very little experience giving advice to those with far greater experience (this often results in either flat-out incorrect or just very basic advice that lacks the nuance to be of use to the original poster) or, much worse, those with little experience advising other newbies who may not have the knowledge to understand what advice might be useful and what might not work or might even do some damage to their relationship with their dog, their dog's understanding of his job, or the welfare of the sheep. It's not that I think people with more experience shouldn't ever be challenged on their advice or that there are only certain ways to do things and I am not being open-minded, but I do believe that the value of all stockdog advice is not the same across the board, and I wonder if it is a bit harder for those advice seekers with less experience to weed out the wheat from the chaff when they have a harder time knowing the identities of the people posting. I think this can be frustrating for some experienced handlers to see and be part of, so they have migrated over to Facebook.
This is just my opinion, of course. I am as anonymous as anyone else here to those outside the stockdog world, with my screen name on an account I created when I joined these boards in 2004, when it was the norm to create a "fun" online pseudonym rather than using my actual name. I am sad that the vast majority of the discussions on the boards have turned away from a working focus, and I consider myself extremely lucky to have been a member when lively discussions on working dogs were the norm because I really learned a lot from them.
