More closely link the “meta-xyz” sites with the xyz sites.
With all these wonderful new StackExchange sites, I find I'm not as vigilant about participating in Meta as I was when I only visited one or two.
Now that the meta-sites are more integrated with the parent sites, I think it would be nice to see some notification on the parent site when you have responses/notifications on the associated Meta site. It could be as simple as having the a separate envelope icon to light up for Meta-notifications.
Anyone with me?
