How to link multiple blogs together

I think its creating a network, but if anyone could give some guidance for what I want to do that would be fantastic:

I have multiple websites I use. one is a magazine that I write on with others, some others are personalized websites for different things. But I blog on all of them. I am making a website that is all about me (egotistical I know) but I was thinking about how cool it would be to have all the blog posts I write on each website to also appear on my personal website. But it would only be the ones I post, not others from my magazine that others post.

Does this make sense, but more importantly, is it doable??
