10 blog mistakes

I started blogging only one month ago and am getting pretty addicted to it. Have met new creative minds and many people with the same field of interest. Found these 10 blog mistakes I shouldn't make by Jakob Nielsen (summarized):

1. No Author Biographies :-)
2. No Author Photo :-)
3. Nondescript Posting Titles :-)
4. Links Don't Say Where They Go :-)
5. Classic Hits are Buried :-)
6. The Calendar is the Only Navigation :-(
7. Irregular Publishing Frequency :-(
8. Mixing Topics :-(
9. Forgetting That You Write for Your Future Boss :-(
10. Having a Domain Name Owned by a Weblog Service :-(

hmm..'think I won't be making money out of it..
