Summize: Making Twitter More Useful

A friend pointed me to Summize today.  Summize allows you to search Twitter's feed by keyword.  Even better, it allows you the option of subscribing to a feed for your search.  In principle, "microblogging" via services like Twitter provide more immediate news coverage than publishing to blogs or traditional news outlets.  What I don't know is how long the lag time between an item's appearance on Twitter and its appearance in your feed reader would be.  But I suspect it's a lot shorter than the alternatives.   So, I suspect what Summize has done will be very good for both of them, and that other media will rush to aggregate or copy Summize's service.  Hope their server hamsters are well fed, or that they're renting Amazon's. (BTW, it appears Summize has narrowed the scope of its service.)
