I tried posting my latest journal entry to the Front Page about 20 minutes ago and its yet to show up, assuming it will.
The comment settings are still locked to public just like a typical FP post so I've no idea what the problem is.
Not sure if I have any helpful information (unless browser/os info would be) and I'm not even sure if there's a dedicated redesign bug reporter, I just thought here would be the most ideal place to post it.
