This is silly. 4-ch may be purposely similar to 2ch, but that hardly means it needs to copy to be a good board. Simply emulating them WILL NOT bring the same success, nor will it necessarily lead to happy users. I'd much rather see decisions made for this site made by our own users and staff, not the users and staff of a site that probably doesn't really know we exist.
4-ch should aim to be 4-ch, not a translation/copy.
