A while back I found a website that lists some of the best looking Android Apps.
It's a really good list of awesome looking apps for the phone. If you're into eye candy like I am, then it's a great resource. It has a *lot* of screenshots so it'll kill your 3G connection (look at it on your desktop). Also, select the 'small pic size' option on the left to reduce some load time.
I should note that a lot of these apps need some horsepower - Flipboard comes to mind, so an overclocked kernel is a good idea. Some of them are also 'icecream sandwich only' which means we can't use them on this phone, but there's enough in the list to give you guys some options.
If you read Reddit then 'Reddit Sync' is awesome. It ran fine on the stock kernel with CM7
Wallbase is a great wallpaper app.
Google+ is pretty, but very heavy on resources.
Evernote is great if you need an app for lists.
Feedly is a great looking RSS reader (pretty light on resources).
There's a bunch of stuff. It's nice to look at nice looking apps.
