Oh totally go for it. Your vlog style should be able to reach many viewers. Whenever I can and whenever it's more or less relevant, I talk about Steemit on my channel or on my website. I link to posts I write on wordpress to bring people here if I can. While on Fb it doesn't get much attention, I find that on Twitter and YouTUbe people are more responsive and interested. People are looking for alternatives and they don't know where to look. With videos like your vlogs for example available for them, they get the answer they sought.
You should totally do it! ;)
