Are we moving our Clutter online with 'Tripit' and other services? Backpack will do!

In the past 24 hours only, I read about Tripit and a couple of other services that offer to help you manage things online instead of on paper. Tripit as you might guess offers to be the online repository for all details of your travel. Another site I noticed (whose name I cannot remember) wants to do the same for your family schedule.
