The comments on this site are turned on, but are moderated and I will never publish them.
Well, the comments are an easy way to let me know that something is wrong in an article, allowing me to fix it quickly. But this space is not great for discussions. Think of it as a library: this is not the place to argue loudly about a subject, this is just a repository of knowledge.
So use the comments, but be aware that those are only a direct communication with me, just a little bit more convenient than email. I will work your comment in the text, or ignore it, or ask you for clarification.
Let me know if you want credit for your contribution by providing a link to an email, a profile, a web site…
And if you really want to argue, have a discussion, gather opinions, there are a number of forums you can use for this purpose.
