Mitch Kapor's Weblog is the talk of the net today. He was the co-designer with Jerry Kaplan of Lotus Agenda (I used to use it, btw). Will it be an Outlook-killer? Who knows...but I'll be happy with something that just does a good job with Spam. Poco is better than outlook, but I wouldn't mind better than Poco even if it didn't do anything else.
