Top 10 Blog Design Mistakes

From Jakob Nielsen's Alertbox newsletter comes another "Top 10 ... Mistakes" article. This article deals with common blog design flaws:

• Author Biographies
• No Author Photo (I should get around to this)
• Nondescript Posting Titles
• Links Don't Say Where They Go
• Classic Hits are Buried (Nielsen suggests linking from the home page to pieces of lasting value - I don't do that, but he also advocates linking to earlier pieces in newer postings, which I have found useful)
• The Calendar is the Only Navigation (he argues for categorizing or tagging posts, but this is unfortunately not easy to do with tools like Blogger)
• Irregular Publishing Frequency
• Mixing Topics (covering too many topics)
• Forgetting That You Write for Your Future Boss
• Having a Domain Name Owned by a Weblog Service
