It seems that Gmail is set to read your mind, it now suggests recipients to your emails! No, Mr Brin and Page are not inside your head, the application simply monitors groups you frequently send emails to. If you frequently send emails and sometimes there are some “crossovers”, this is a handy feature which can make sure you don’t leave anyone out.
You can enable this is the labs settings in your account, and once you do, you should see some suggestions come up. For me this didn’t work perfectly because I actually rarely email groups, let alone more groups. If you use email mostly for client-to-client work you probably won’t find this too useful, but in an office-like work environment this could be really handy.
For myself I’d rather like a better contact management system instead, something better integrated with the compose screen, maybe once that can read your first line and decide on the recipient. You could tell Gmail that if you begin a letter with “Hi Daniel” you want to send an email to me. Based on names this could be automated to some extent too. Do you have any contact feature suggestions for Gmail you’d love to see?
