Ecto doesn’t support Tagging. At least they don’t support the tagging in WordPress 2.3 (because they actually do support Technorati tagging but that is something different as you can see in the body of the last post – see the links).
All this means is that I have to use the Admin portion of my web site to do the posts which is not as elegant to me (though it’s much improved from the early days when I first started using WordPress) but it’ll do.
