I'd suggest you look closer at the services that teams are already using and try and add value to those by algorithmically generating what you think is useful for people to know. I agree simply acknowledging what to-do's people have ticked off in the day isn't that useful (BC can already do this for example) but there is room for intelligent insight here. You could determine people's productivity rate towards a milestone and provide predictions if things are on track for a particular milestone date etc. I think then you would have a valuable service. Just my 2 cents ;-)
