Ask HN: Including video elements in a tech blog for employers

I was thinking of starting a blog mainly to show off to tech employers.

I'm wondering if video elements would be good to include in addition to text elements, essentially to shortcut the interview process to establish the in-person checks on the hiring process (Is this person likable enough, are they alright at oral communication, are they not a hugggge jerk) I've read a lot of advice about not including photos in resumes that seems like it would apply, but I'm still thinking it would be a good option. Do you think there are factors I'm not considering?
