2. If I want to follow only selected

of Collections from multiple Profiles? (Yes, I realize that this presumes that there's a standardized naming of Collections. I've suggested that as much would be a Good Thing, particularly, say, Photo , Video , or language-based Collections.
4. Is there a way to assign Collections to a specific Stream? Again, I'm generally not all that wild about clogging my streams with images, but if I had a Photos stream, I could visit that. As it is, I hit Imgur or an image-based subreddit, which is a far better way to manage and curate such content.
