Wanted: Techmeme for Twitter

Wanted: Techmeme for Twitter. Does this exist? Hashtags don’t suffice!

Just posted the above to Twitter. Here’s a bit more on what I mean:

Basically what I want is the ability to group tweets by topic. Ideally this would not just by keyword – it should be able to interpret why someone is tweeting that it’s a “sad day..” based on contextual clues. And it certainly must go beyond hashtags, which are clumsy and often not used.

What’s the benefit of this functionality? It would clean up a user’s stream. It would give a better, more holistic picture of an issue or event. And it would allow users to filter more effectively.

So, does it exist? If not, well, c’mon!
