Is anybody using App Brain? You can set up an account at
www.appbrain.com and download it from Market. It will sync with your phone, so that when/if you flash or change phones or have to reset to factory settings you can easily get all of your apps back.
You can also browse apps on the web and mark them for installation on your phone.
We could also friend each other so we can see what everybody's downloading. LOL Creepy.
But App Brain is great.
