That would be like Pinterest then. I've been thinking about adding a view option for that, my first prototype about 10 months ago actually worked exactly like that since it's a lot easier to do than the columns scrolling separately:

I don't think it's actually more convenient, but it depends on how you use the app. If you just want to get a quick overview it probably is. I leave the app open all day to see new posts scrolling in as they are made, and to keep tabs on my own posts, see new upvotes and comments and things like that.
