YES! I have a blog binder and I LOVE it! I put it together a couple of months ago, using some lists from ListPlanit and a collection of my own spreadsheets/word docs.
Here's what is in my binder:
1) Weekly planner... I schedule posts for each day of the week... and also plan in advance to work around giveaways, holidays, etc.
2) Blog ideas: These are for ideas I have in my head that I can put together at anytime. I list potential post titles, points I want to make, and sites I want to link to.
3) Affiliate Info: All the affiliates I belong to, as well as logins and passwords (too many for me to remember these days!)
4) Income - It helps to realize those few dollars add up!
5) Expenses _ I think I'm just going to merge these two tabs together at some point. We'll see.
6) Goals - these are a collection of short term and long term goals for my blog and steps for how I plan to reach those goals.
7) Social Networking - ideas for social networking, logins, campaigns, etc.

Publicity - all print, radio, and television media that has mentioned Northern Cheapskate. (this is more of a confidence boost for me than anything else!)
9) Books to Read - Frugal living books I want to read... I periodically review books for my blog, but when I get to the library, I forget what book I was looking for. :-)
I LOVE MY BINDER because it allows me to work on my blog even when I don't have access to the internet. With three little boys, it's hard for me to get online during the day, but I still get ideas during the day. With the binder, I can write down an idea for my blog right away so I don't forget.
I'm a planning junkie, so what I do may not work for everyone. But it works for me!
