Feedster News Alerts are like Google News Alerts that cover blogs instead of mainstream news sources. Useful for checking blog or news coverage on very specific topics.
While news alerts services like these are useful, they have severe limitations. First, it's a pain to set up these services, providing lists of specific keywords that match your interests, then refining them if they return too many or too few results. Second, as anyone who's used these services knows, you rapidly become saturated by the unprioritized flood of news alerts e-mails coming into your inbox.
Combining all the e-mails and properly prioritizing the combined results would be a step in the right direction. At the extreme, when everything is easy and well prioritized, you may end up with something that looks a lot like the Daily Findory News.
