Scheduling posts will work not only for the short term, but for long term writing as well. Say, for example, you purchased some articles from a writer and wanted to implement them on your blog every week for a year. You can easily do that by scheduling them. Imagine how nice it would be to spend a few days getting your posts written, and then not have to worry about posting them for weeks, or even months.
Scheduling is great for planned away time, too. If you know you will be on vacation, or just too busy to spend time blogging, you can schedule posts to go out automatically, leaving you free to enjoy your time off.
I like to sit down once a week on my own blogs and write out all of the posts for the week. Then I schedule them for whatever days I prefer and can be free to do other work for the rest of the week.
Schedules aren’t set in stone, either. If you wrote a timely post on a news article, only to find that it is no longer relevant or needs to be rewritten, you can just remove it from the schedule and move on.
In both Blogger and Wordpress, scheduling is done right from the new post page. Instead of posting now, you can set a date and time, and then hit publish to schedule it for the time you indicated.
Scheduling can take some of the headache out of regular posting, and free your time for other projects.
