Clean up my contacts. This one is on my list every year, but it has never been completed. The problem? So many of my contacts aren’t even in my contacts ( that is, my iCloud/Gmail contacts) – they’re just in my email. That’s whereWriteThatName comes in. For a mere $30, the service will scan through my past emails and update my address book using the info it finds in senders’ email signatures.  Uh, genius. Then for an extra $35, I can keep this going all year long.

Not bad! 😉
