Maybe you are like me, because it was with absolute certainty as I looked forward to the twenty first century, there would be really useful technology to make life easier and more interesting. Sure, sure there is GPS and Roomba - but I mean 'Killer Apps' that are more than really cool toys. Something I think about all the time is how Microsoft (and the entire computer industry) apes the wonkish love of Bill Gates to be handcuffed to a computer. Call me a heretic, but I want freedom from the screen.

That's why it is great to read about SP's own Andy MacDonald in the Seattle Times business section "Interface" column today. MacDonald's killer app is called Blogarithm.

Blogarithm tells you when blogs and websites are updated. Face it, after reading hundreds of "pages" of web content - in order to keep current with those things that interest us - now we have to keep up with the changes. That's what Blogarithm does, via one nice compact e-mail per day. It has applications for your family reunion Aunt Tilly is planning next summer, and all those hobby sites you follow. But the really killer app is your abililty to track a multi-faceted business environment (dozens and hundreds of clients, colleagues and competitors - both web pages and blogs) with that single daily e-mail.

I call that liberation.
