Is going through the Windows Shop within Windows 8 the only way to know about the apps that are currently available (and if an app idea is already taken)? I've seen Windows 8 app links like this one - http://apps.microsoft.com/webpdp/en-in/app/bigflix/cd3aa73b-e60e-44b6-bbe9-6898050a3502
...but going to the root site throws a "403 - Forbidden: Access is denied" and a search for "Windows 8 Store" doesn't provide any useful results. I guess there will be something after the official Windows 8 launch but is there anything else I'm missing? As a developer, I would love to see a summary listing of apps that shows a brief description, its features and Capabilities used.
Unfortunately for us, Microsoft is not providing any such information regarding the Store apps. All we can do is glean a bit from here and there. Zdnet has mentioned the number of apps, for example.
This link in particular maybe of some use because it provides estimated app category breakdown.
I created site http://metrostorescanner.com/ to see what's new in apps for all countries (but you can also use country filter).
I found a file with a site map that you may be able to use for a listing of apps: http://apps.microsoft.com/webpdp/sitemap/sitemap_1.xml
http://www.greatwindowsapps.com is a searchable directory on the web. It's not the entire Store, the content is filtered to remove poor quality apps. Disclosure: this is my site, so clearly I think that's an advantage :)
http://drunktester.azurewebsites.net/ is the full Store using the Australian content. He published the source code (https://github.com/VikingCode/DrunkStore) so you could set this up for any country if you wished.
Update - It is now possible to search for Windows Store & Windows Phone apps even from non-Windows 8 machines and also view apps by category from the official Microsoft websites.
As @mamata-dalal & @gyurisc have mentioned, there is currently no official Windows 8 app directory.
I came across the website Windows8Apps (though not perfect) that comes close to what I'm looking for.
Currently there is no other place than the Windows 8 Store is the only place, but I am sure soon there will be plenty of sites categorizing these apps.
