Google Buzz appeared in the Gmail inboxes of millions of users last week. Does it matter? I’m not sure it does.

I’ve used it a little bit. I hooked my Twitter posts, blog posts, Flickr account and a few other things to Google Buzz, so anyone who’s following me will see those items in their Buzz stream. And I’ve seen other people’s blog posts and photos in there, too. I’ve even occasionally commented on things through Buzz.

And of course, you can post directly on Buzz, too. It’s similar to posting a status update on Twitter or Facebook, but there’s no length limitation as far as I know.

I’ve posted and commented on a few of these updates, but these have mainly been updates about Buzz. I’m still posting my everyday updates on Twitter and Facebook rather than on Buzz.

There is a convenience factor to getting updates about people’s blog posts, photos, shared items on Google Reader, etc., right in my inbox. But I already get these updates elsewhere. I read blogs through Google Reader. I look at photos on Facebook and occasionally on Flickr.  Or people post their photos and links to their blog posts on Twitter.  So Buzz doesn’t provide me with anything I don’t already have.

If Buzz adds functionality for more web services, like Delicious, WordPress.com,  GoodReads, etc., I might be more interested. I already have a Friendfeed account, which aggregates these kinds of updates into one stream, but I only go there if Twitter isn’t working.   If that kind of stream were right in my inbox, though, I’d probably use it.

Buzz in the workplace could also be interesting. I’ve heard that at some point, Google will integrate Buzz into Google Apps, which my workplace already uses for email, websites, calendars, documents, etc.  Having a Buzz system available for workplace conversations could be useful; Twitter isn’t really conducive to communicating within a certain group.

For now, though, I might just ignore the Buzz.
