Pardon! You're right. I deleted "impressions" which obviously were much more than 7K :-) The ratio is still the same.

On youtube you can post videos to gain followers to steemit haha

I guess it depends on how successful you're already on YT. If you are one of the big players there, then obviously the smartest move would be bringing your audience over to steemit (like several youtubers have already done in the past weeks :-)).
I'm just a little fish in this big YT tank, so I guess I won't catch too many there, hehe
