I would agree with Preparedwithlove and would add Ciccio & StarryDelight. I find them both very helpful with their posts and have seen them share a lot on their FB sites as well. Lots of others but these come to mind right away. Elli & Goreti too would be a good as they are both so supportive in the community, like Ana whom you guys have already interviewed.
By the way, I love the interview series and find it helpful in many ways. Love this site too!
