It seems that Google is deeming the ramblings of Twitter users as newsworthy. As Mitch Joel explains:

For obvious reasons, the term “mitch joel” is set as a Google News Alert for me.[...]

I was shocked to see this one from last night:

Mitch Joel: Power Within Ottawa comes to a close. Back home in Beautiful Montreal. My brain is fried. I've met/talked with too many great people today.
Twitter / Mitch Joel - http://twitter.com/mitchjoel.

Yup, Google is not only parsing and indexing results from Twitter, but it is considering it Google News Alerts worthy. This is a powerful paradigm shift towards acknowledging all content as news worthy.

If you thought we knew too much about individuals because of Blogs and Podcasts, Twitter will, literally, melt your brain.

I can't help but wonder if this might render Google Alerts completely useless for a lot of users and their terms. I mean, granted, there are definitely a lot of PR and marketing types that will want to be able to gage what the general consensus is about their clients and companies, but if Twitter catches on like Mitch thinks it will, then Google Alerts will be mostly swamped with babble that grossly irrelevant for most users.
