Sometimes, you come across a piece of technology so blindingly obvious, you wonder how it didn’t already exist.

Consider Kwaga’s excellent WriteThat.Name: it plucks information from people’s email signatures, and uses it to update your Gmail contacts.

It’s so effective, I’ve now stopped manually entering contacts into my address book, and simply synch my iPhone directly with my Gmail contact list.

Definitely worth giving WriteThat.Name a try yourself.
