Wordpress or Posterous?

Right now I’m debating the qualities of this Wordpress blog & my newer Posterous blog.  Each could serve different purposes, and each has its own qualities.  But at the end of the day, the platform matters a lot less than the dialogue within it.  And there’s a lot less dialogue happening on this Wordpress blog than with Posterous.

For now, I’m keeping both. I’ll be experimenting with posting deeper commentary about account service and digital marketing on this blog, and save more anecdotes for Posterous.  But it’s entirely possible that I’ll merge the two down the road. Do you use both?  If so - are you considering merging the two or keeping them separated to serve different audiences and purposes?  I’m curious to know.
