Weird - Posts Aren't Showing Up

Does anyone know why certain posts show up on other blogrolls and others don't?  For example, I made a post last night about Disneyland that appeared on various blogrolls.  And frankly, it was a so-so post.  Nothing special!  :)

But then I made a post this morning that I really liked about a re-tooling of the B/X Thief class.  I was hoping to generate some discussion and share my proposed fixes to the Thief class, but lo and behold - it didn't show up on any of the blogrolls that my posts normally show up on.  None.

So this posting is kind of a test to see if it will show up on the blogrolls - and kind of a question to see what causes certain posts to not appear. 

Has anyone run into this before?
