Am guilty of this. I often write sumpthin' and instead of posting it right away, I put a date and/or time in the future. Then I click on "Save Now". This allows me to have blog posts for each and every day.
Blogger did something about this common action. So after writing down your thoughts, you can click on "Post Options" and specify a future date/time. You DON'T need to click on "Save Now" anymore. Click on "Publish Post" and your entry will be posted on the date (& time) you provided. Cool, eh?
For example, it's now 4:51 pm (Friday). See you in the future!
