A top ten list of blog design usability issues.  Short version:  make it simple for new readers to find what they want & understand who you are, so they can explore & make a decision about you.  Other tips:

1. No Author Biographies

Unless you’re a business blog, you probably don’t need a full-fledged "about us" section the way a corporate site does. That said, the basic rationale for "about us" translates directly into the need for an "about me" page on a weblog: users want to know who they’re dealing with.

It’s a simple matter of trust. Anonymous writings have less credence than something that’s signed. And, unless a person’s extraordinarily famous, it’s not enough to simply say that Joe Blogger writes the content. Readers want to know more about Joe. Does he have any credentials or experience in the field he’s commenting on? (Even if you don’t have formal credentials, readers will trust you more if you’re honest about that fact, set forth your informal experience, and explain the reason for your enthusiasm.)

2. No Author Photo

Even weblogs that provide author bios often omit the author photo. A photo is important for two reasons:

• It offers a more personable impression of the author. You enhance your credibility by the simple fact that you’re not trying to hide. Also, users relate more easily to somebody they’ve seen.
• It connects the virtual and physical worlds. People who’ve met you before will recognize your photo, and people who’ve read your site will recognize you when you meet in person (say, at a conference).

A huge percentage of the human brain is dedicated to remembering and recognizing faces. For many, faces work better than names. I learned this lesson myself in 1987 when I included my photo in a HyperCard stack I authored that was widely disseminated on Mac-oriented BBSs. Over the next two years, countless people came up to me and said, "I liked your stack," having recognized me from the photo.

Also, if you run a professional weblog and expect to be quoted in the press, you should follow the recommendations for using the Web for PR and include a selection of high-resolution photos that photo editors can download.

3. Nondescript Posting Titles

Sadly, even though weblogs are native to the Web, authors rarely follow the guidelines for writing for the Web in terms of making content scannable. This applies to a posting’s body text, but it’s even more important with headlines. Users must be able to grasp the gist of an article by reading its headline. Avoid cute or humorous headlines that make no sense out of context.

Your posting’s title is microcontent and you should treat it as a writing project in its own right. On a value-per-word basis, headline writing is the most important writing you do.

Descriptive headlines are especially important for representing your weblog in search engines, newsfeeds (RSS), and other external environments. In those contexts, users often see only the headline and use it to determine whether to click into the full posting. Even if users see a short abstract along with the headline (as with most search engines), user testing shows that people often read only the headline. In fact, people often read only the first three or four words of a headline when scanning a list of possible places to go. Sample bad headlines:

• What Is It That You Want?
• Hey, kids! Comics!
• Victims Abandoned

Sample good headlines:

• Pictures from Die Hunns and Black Halos show
• Office Depot Pays United States $4.75 Million to Resolve False Claims Act Allegations
  (too long, but even if you only read the first few words, you have an idea of what it’s about)
• Ice cream trucks as church marketing

This last headline works on a church-related blog. If you’re writing an ice cream industry blog, start the headline with the word "church" because it’s the information-carrying word within a context of all ice cream, all the time.

In browsing weblog headline listings to extract these examples, I noticed several headlines in ALL CAPS. That’s always bad. Reading speed is reduced by 10% and users are put off by the appearance of shouting.
