Blog and/or forum inside portfolio?

[Néstor Llamas Llopis]

Hello,

I just want to know if a blog section and/or a forum section would be suitable for a website destined as a professional portfolio.
For example, a portfolio website maybe should never include a section about news or sports, as well as it should always include a section about the personal CV, but I don't know if a blog or a forum are ideal or convenient for the portfolio purpose.

Regards,
