I used to post something every weekday. Then I read somewhere that a post left up for a couple of days will get consistent traffic and give people time to find it.
I put up a post last Friday and I got 157, 176, and 97 views over three days.
New post two days ago and got 115, 104, and 84 today (so far).
I think posting every day when you're brand spanking new is a good idea since you're probably only getting your family and friends to read it. Once they've passed it on or you get some "unknown" readers and search engines can find you, you can relax and put more time into each post.
@tltcl You're right about fresh content. The first 3 or 4 weeks of my blog have some embarrassing posts. I sounded like a raving madwoman. :-)
