My new goal: Make my Gmail account usable again.
I started about 10 minutes ago with 10,000 conversations and between 1000 MB and 1050 MB of e-mail in my Gmail account.
I'm currently down to 6881 conversations and 939 MB in my Gmail account. Time to take a break for the kids' bedtimes, but from now on, I'll be taking an aggressive approach to subscriptions. If I skip over an e-mail update, I will now be immediately unsubscribing. I'm not getting reasonably important e-mails at the moment.
