On my current Movabletype page at http://heathallyn.com/human/
I have my main blog, and at the top of the page I have a little box with a Haiku. In MT, I accomplished this by having my main blog, then a separate Haiku blog, and I used the "Multiblog" plugin to just pull the latest entry from the Haiku blog to display at the top.
I initially had experimented with having my Haiku as a separate category in my main blog, and then had my index display all categories EXCEPT Haiku, and the box only displayed the Haiku category. The problem with this method was that if anyone just picked an entry to start at, and then clicked "next entry" because they just wanted to read through all my entries, they would have to wade through tons of Haiku in the process since there was no way to exclude the haiku if you were just clicking next or previous entry.
Is there any way to accomplish this in WP through inherent features or plugins?
