Y'know how on Facebook or Twitter or Google Plus it's coded so you can easily link to someone else's profile by typing it "@hoobajoob" or "+hoobajoob" in your post?
That'd be a neat thing to add to the forums and Lodestone blogs for linking to profiles of people we mention.
Also, adding something to bring up a pop-up item description when we mouse over an item name in someone's posting would be cool, too.
