How often content is posted to a blog, I feel, has a lot to do with its niche. If it is a how-to blog, or some type of personal journal, or something along those lines, you can get away very easily without posting new content every day. However, if your blog is more news based, then you have to try and post content daily (and even multiple times a day!)
On my site I try to post new content daily since it is mostly news articles, but sometimes it gets difficult to keep up with.
