"Out of curiosity comes everything."
The downside to the many easy, instant and cool blogging platforms on the Internet is that it is really easy for Internet-active folks to suddenly discover they have started a few too many blogs, joined a few too many social networks, and have created too many points of presence to keep up well.
I have a one-page chart that anyone can make that has helped me manage two things: keeping focus and awareness on my important blogs, and easily channeling blog post ideas to the right blog.

One blog isn't enough for me. My professional readers don't really care about my personal life, and my Second Life friends don't want to read about my linguistics hobby, for example. Readers spend time on blogs they trust to be about the topics that interest them. No one likes a blog that wonders everywhere.
And yet, twelve or twenty blogs is too many, if I were to set up one blog for each favorite topic of mine. Something between these two extremes is the right balance.
So I made a chart for my wall; I pinned it up right next to my computer screen (same visual field). The instant visual awareness does four things for me:
So this chart keeps my focus while inspiring more ideas - ideas that fit the focus. Nice.
Here is an example of my simple chart idea. You'll have to make your own and fill in your own keywords and blog names. There's even a spot for your Twitter, Flickr and other blip-style channels at the bottom.
And may your day rock the house!
