One Blog to bind them...

I've got 3 blogs right now - this one, a running one, and a personal "Catch All" one for stuff that doesn't fit in the first two.

What I really need is one blog with tags, and a way to publish a "tag filtered" version to the people I know who read them. 

Another technical challange is to embed google map tracks of my runs into the running blog.  I could simply do an image publish, but I'd like it to be single click type functionality.
