The other example I have is a relatively new service that I love: Noteleaf. To use Noteleaf you simply allow the service to have access to your Google Calendar and LinkedIn accounts and when you schedule a calendar event, Noteleaf goes into your LinkedIn account and looks for data on the names used in the schedule item.
The data on these people is then added to the comments field of the appointment in Google Calendar giving you some great prep for your meeting.
Even better, Noteleaf will send you an SMS reminder just before the meeting which includes, for the identified people, their picture, LinkedIn data, a link to your recent Gmail exchanges with them, and, if your calendar entry included the location of the meeting, a link to Google Maps.
This is a genius idea! It's like having an assistant that never misses providing you with the information you need to be prepared for a meeting.
Mark my words; this type of Web application enhancement of data is going to quickly become a big trend and will, in turn, have some interesting effects such as making people pay more attention to putting their details on line and making sure the data is accurate.
I highly recommend both Rapportive and Noteleaf ... they are both not only really useful but they are great examples of how the Web of the future will behave.
