Multiple blogs on the same site.. is that possible?

I’ve recently gotten back into blogging and enjoying it a lot.

There are some interesting things going on in my life and I’ve decided to blog about those in multiple blogs. But rather than have my friends visit 4-5 sites to follow me on all subjects, I would like to have them visit one site and visit all the blogs from there.

Is this possible?

What I mean is, can some click on a link on my blog and visit another page on the same blog that is for all intents and purposes a fully functioning blog on its own? With the same template as the other one.

Is that possible?
