Hello everyone!
This site is powered by VBulletin. I know another site powered by VBulletin, and on that site you can see which members are currently viewing your thread. Even if the thread/forum wasn't created by you, you can still see people looking at the thread.
I think this would be a great idea to add to this site.
Also, the other site I know has an option where you can create a "userpage" using code. A userpage is basically a website, but on that site you can give some background info on yourself, such as hobbies (nothing too personal), you can show off your code skills, you can talk about different cool stuff you did, interesting threads you created and links to them... That site was also a forum for a video game, so you could talk about that video game, your character...
I also think that would be a great idea for this site.
But again, it's up to the Wrox team.
