If you can avoid making any references to other blogs then should be able to limit the chances of:

1. Anyone else finding out about you
2. Learning about other interesting topics to blog about
3. Your Google Ranking ever increasing
4. Helping out your visitors by referring them to other useful information

You don’t want anybody to find you anyway, right? If you don’t need links to other blogs then this avoids the need to read other blogs, so this will save you a ton of time. Also don’t forget that Google values pages that link out to other relevant pages. You don’t want Google to think you are valuable, do you?

Finally, your blog is just for you anyway, isn’t it? Why should you help your visitors when they do find you?
