So I follow a bunch of artists on YouTube and they do occasionally do livestreams on U-stream. My main problem with that is A - I work all day and B - when I try watch it later, there is too much chatter and people signing on and asking questions and you're only hearing one side of the conversation.
I do like Barbara from Joggles, because as some of you mentioned, she tells it all and there isn't a lot of chit chat that is off-topic.
FYI - I follow MixedMediaJenn, Cat Hand, Shannon Green (who doesn't post as much as she used to - she's now a rep or designer for Canvas Corp) but watch her older videos - she chats a bit but she has some fun ideas, Kiala Givehand - again not so active but she did a book a week a few years back so there is lots of info on different books to make, Carolyn Dube - she's a kook but her videos are usually short and sweet. She also has a huge back log of videos about Gelli printing. PackerDi and Jenniebellie now mostly have pay to watch things but again you can go back and watch their early free stuff. I like Teesha Moore and Donna Downey and I do pay to watch their stuff.
EDIT: There are still free videos - Donna Downey Artists Gang. They are posted on Tuesdays and it is a group of 6 artists for one year - there is a video for today here:
Cat Hand started a series last year called Mixed Media Morsels - I think there are about 30 videos. Short and easy techniques for creating backgrounds, lettering and using up some of your scraps.
I'm also taking Tammy Garcia's/daisyyellow Groovy Grunge class which started Dec. 27 and I love it so far. I'm working in an old book for this one. (She's gypsy999 on Instagram and Flickr.)
