Techmeme is filled with major tech sources covering Microsoft's Windows 7 debut (TechCrunch, D6 Highlights, WebWare, Engadget, and many more). But the action is also being covered actively (perhaps even more actively) on Twitter. In the last two minutes, John Battelle, Jason Calacanis, Loic Lemeur and others have tweeted updates, insights and analysis... starting conversations and valuable dialog.

It's well known that Twitter is as much a short-form of blogging as it is an instant source of news. In fact, one of the first users I followed was @redsoxcast - a user that broadcasts nearly every Red Sox pitch. I pay for's service - but actually prefer following @redsoxcast because it is portable and always accessible.

What I am struck by, however, is that this is the first robust, instant dialog I have followed on Twitter. I have followed one-person updates before (like the Oscars or Red Sox games... but I haven't yet seen this level of interaction. Of course it's covering a tech event... but if Twitter can amass this sort of activity across multiple, they will be a major player in news and a major competitor to bloggers.
