Oh, yeah, I liked this idea when it was Action Comics Weekly.
In practice, though, it means tying together what could be several different series with different readerships. It will hobble sales on all of them as each reader finds that he dislike a majority of features.
Also like ACW, there's a Green Lantern strip. Because DC still doesn't get that Green Lantern is too ridiculous to even include in an anthology book. It'll only depress sales, because it's a stupidly over-powered magic-hat character. Also, it's Hal, so I want nothing to do with it.
