Thanks to Dan Karleen for pointing out how one can subscribe to Google Alerts via RSS feeds. I personally prefer this to receiving emails. And this solves my problem: now I can get both Google and Technorati alerts in one convenient place; namely, my news aggregator. (I use SAGE.)
All you need to do is go to http://www.news.google.com, then key in the word or phrase you want to track. You'll get a results screen like this:
Then you just click and drag the "RSS" icon into your news reader, and you're set.
