I prefer to type with several clips by nonverbal info - it's based on my experience where impressions differ with lesser possibility with the more clips I saw. Here we have similar situation - you are using nonverbal for reading info related to a type.
> You linked only one clip for each and it's not always easy to find a second one, apparently.
Every link leads to a clip on a channel, - you may open other blogger's clip there. It's not so hard.
Eh, I ran into the issue of not finding another clip pretty early on. But I'll just skip the ones that don't have an easy to find 2nd clip, then.
And sure, I asked because I don't want to mess with the validity. (Not that I'm not skeptical but I don't mind trying to help with the project.)
