With the world turning into rich internet applications (aka 2.0 world), I wonder why there aren’t more useful 2.0 applications that help me deal with personal relationships.

1. Predictions
There’s farecast for predicting when flights will cost more. But why isn’t there a tool out there that will tell me when the best time call someone is? Or when they will actually answer the phone and not let it go to voicemail? Or better yet, tell me when someone is too cranky and needs a cool-off period. Or simply, warning, someone has PMS–be careful around her. If a 2.0 tool can do that, that would be nice.

2. Recognition over recall
More than ever, I don’t have to keep a vast knowledge of names, figures, movies, and what DTMFA means anymore. Thanks to Wikipedia, urbandictionary.com and now image recognition. But how about a 2.0 tool that could tell me…if I was making the same mistake again. George Santayana’s quote those who do not remember the past are condemned to repeat it would be handy now.
