2. Calendar....OK, which I made with excel. This way if I have a strangely open hour or two and I write feverishly, I can spread out my posts. I also mark the pub dates of all the books I get from freshfiction.com so I know what order to read them in (oldest pub dates first). Really, this can be so helpful to see at a glance which days you've schedule posts. I highly recommend it.
3. Daily schedule. I have an atrocious habit of doing things as they strike me, so scared am I of forgetting to do something. I try to work against it by giving myself certain days for writing to certain blogs. I also designate certain days for cleaning, laundry and grocery shopping. It helps me to focus on the task at hand---I can tell myself "Yes, there's laundry to do, but laundry day is Monday, today is Saturday, so let's finish up this post." Sometimes, things get away from me and I find myself not writing in order to do dishes that have been sitting for a few hours, but really (truly!) I get MORE done by following a schedule. Otherwise, I'm doing dishes, then wiping down counters, then stopping to run something to its rightful place upstairs, then pausing to wipe at that spot on the mirror, etc etc and basically doing everything but BICHOK (butt in chair, hands on keys). In other words, for me, a general routine helps me to write instead of spin my wheels. It also means I can work on posts in the morning and my novel in the afternoon. (which I haven't been doing lately!) Also helpful: I've realized now what is reasonable and what is unreasonable in terms of expectations for my daily time with kids, their nap times and running errands. For example, I will probably not be writing for Technorati anymore, nor will I be copying and pasting my blog posts into Bloggy Moms---there isn't enough time in my week!
All in all, you need to do what works for you, what is easiest and what dovetails with your natural inclinations/habits/lifestyle. But overall, I highly recommend some kind of organizational system, especially if you are a freelancer.
