There are several ways that you can find blogs that are of interest to you.

You may be forwarded a link to a blog, for example, in an email.

You may find a link to a blog on another webpage or another blog.

You can search for blogs based on topics that interest you.

Here are 2 blog search tools:

1. http://blogsearch.google.ca
   
   
2. http://technorati.com/
   

Try either (or both) out and see what comes up !

Cheers.
