I have mainly done portfolio sites as a way to practice or try out something new. I like that as a side project because it can be a relatively simple content site to get a feel for the technology. There is even room to expand by making it more dynamic with a publishing feature.
I can see how that may not be the same for others. If you are more into having a solution that works out of the box, I don't think there is anything wrong with that. From your post, it seems like your preference leans towards getting blog content out there, so I think WordPress is the right tool for the job. If your site was more of a static content site, I would think that it would be more work for minimal gain.
Setting up a portfolio site sure is good practice. I think I just got bored of redoing the same thing over and over again with different technologies.
I did learn a lot from all of those projects but now I just can’t see myself doing it anymore. :)
