It's my favorite, so far. A few things could be better. Like when you have large cards set, you still have to click to see the whole image of posts. Most of the time it's only cutting off the top and bottom so it's annoying when it should just show the whole image. Some other small things like that. But otherwise the best I've tried so far!
Edit: I think I'd like an option to enable the karma calculation to be visible or not, now that words spreading it's actually there.
