Google Reader Shared Items Websites

A year before, websites showing shared items in Google Reader were the talk of the industry. But none of them have kicked off like a Next Digg and some have even closed down since:

1. RSSMeme – My favorite website and the only website seem to be running.

2. ReadBurner – Under revamp now. I liked its first version. After it was relaunched by a company it tried to do too many things and was confusing. I hated the color scheme too.

3. FeedHeads – Closed down now.

4. Shared Reader – Disappeared !

Some reasons I could think for this withering trend:

* Google Reader keeps improving its social features that a need for a third party site may be less felt.
* Most of the startups have been single developer projects, who might not have found the time to promote the sites.
* Services like FriendFeed which show not just the Google Reader items but all social media activity may be more attractive.

However, it still would be great if Google itself comes with an interface like to show case most shared items topic wise and language wise.
