Help Finding Specific SEOMoz Blog Post - Help meh puhleeze

[bashseo]

Hi everyone!

Hopefully everyone had a great weekend.  I'm having trouble finding a specific blog post (from the SEOMoz blog), that was pertaining to content writing.  I think (but could be wrong), that it was written by Rand, but I'm having the most difficult time finding it.  The overall theme of the post was about Writing/Blogging about topics OUTSIDE of whatever your niche is.  I didnt bookmark the thread (doh!), but the theme of it was to basically not just write about stuff pertaining to your niche on your blog. but to write about other topics as well (I.E if I have a site about blue widgets, not only writing about blue widgets).  Is there anyone that is familiar with the post that I am referring to that could possibly point me in the right direction?

Thanks a ton
