I found this today. It’s apparently some kind of presonal organizer from 37signals, the people who made Basecamp and Ta-da List. It sounds neat, but I have this nagging feeling about ideas like these. I think that the reason why some of these things work is that they are centralized, and that one of the major things we need to do as web developers (those who are) is work out how to decentralize everything.
Look at Livejournal. Livejournal is a community that people on the outside (myself included) don’t really understand. The functionality afforded by their application is not as slick as many of the free blogging software solutions. The trick is that it also provides collaborative friend and interest lists, which is impossible to do with stand-alone blogging software.
