How do i find my way around a blog?!?!?!?!?!

the way i find my way through a blogs is that i look on the side to see if they have any specific topic's if i wanted to find something mostly tabs then i look at the post and i figure my way through blogs as i go on.And if i wanted to find my friends blog from mine then i would add them as a friend on my dashboard then i will look at their blog when i click his/her name.
