So, usually I have a couple of blog-post-ideas in the wings at any given moment. Because dang it it's hard to come up with an idea on the spot every week. So I come up with stuff, write it down, and shelve it. Some posts I've been working on for months on the back-burner - I'd like to do a "Form Doesn't Mean Formal" post about sonnets, but a) I "used" one of the sonnets I'd been intending to use for that post in a different post, and b) I try to meet certain metrics whenever I do a "Three Poems" post - I try to include a female and a foreign writer in each mix - so it's staying on the back burner til I can meet these metrics. Usually I know whatever post I am doing next though of course with topical stuff it changes.

As for "popular misconceptions about poetry" I have had a similar idea but a little more personal. I'd like to do a post about "things in poems that give me pause." Like, little red flags that I may notice in a poem that start making me think twice about whether I want to keep reading it. Cats are actually one of these red flags, as are gerunds. AND, couplets especially with syntactically garbled lines. It would be a more personalized post than your suggestion. I do like your suggestion but I've noticed I'm not comfortable making sweeping generalizations about stuff. However, on the other hand, there are certain mistakes that beginning poetry writers do make over and over again and the aforementioned couplets and "garbled syntax is okay" are definitely among those. Part of it is that I don't want to seem like a pundit coming down from some place "on high" saying "Don't do this!" You know, like what room do I have to tell other writers what to do?

Popular misconceptions about poetry could take a different bend than that though. I would like to take a poll first! That could be fun.
