Hi. As you can see I don't post much on GFY because I like to read

About 80 posts in 5 years on GFY, and I am visiting GFY every day
So, I have one question and as I can see there is many many pro bloggers here and maybe someone will help me
It's about blog network linking... For example, I am doing 5 niches and have a network of 20 blogs, and for example 1 niche - 3 blogs (like 3 blogs hardcore, 3 blogs teen, ... so 5 niches = 15 blogs) and the rest 5 blogs are general (all niches) blogs...
So for this example, what would you recomend me for linking all the blogs in the network?
Putting all the blogs in the blogroll? Or linking the keywords in the posts to the other blogs? How to link for example teen blog with shemale blog and have good results in search engines with that? And so on...
I know you have the knowledge in this matter, but I hope someone have time and good will to share that knowledge with me and the others willing to learn something
Thank you in advance
