Oh I see, that's a fair point. Perhaps in your case it makes sense to have some presence when you know that people may you look you up. Although, I would still argue that should not be reason enough - unless that it is, you actually want to have a personal website and enjoy writing.

In my case, I often feel like my opinions are so asinine and generally not worth sharing that I just don't feel the urge to set them in stone, so to speak.
