That's a great question. I'm glad I asked it. An SEO rant is the impassioned discharging of SEO information. There are many forms of SEO ranting. One could rant about how horrible or annoying or repulsive something about SEO is. There are also more positive forms of SEO ranting. When one sees an amazing new advent within the SEO world or stumbles upon a fascinating SEO occurrence... these are rant worthy. In such cases, the rant is less a toxic discharge of knowledge and more some sort of religious SEO experience. The point is, defining what an SEO rant is can be tricky as a good SEO rant is a piece of art. But not the kind of art you find in a museum, more like the art you find in some deranged neighbor's attic. Anyway, I hope this clarifies things a bit.
