The fine folks at Geek & Sundry are trying to get up to 500,000 subscribers. They’re good folks (Never met them, but they all seem nice.), they have a nice geek blog and they help bring you your favorite web series, The Guild, so you go help them out.
As an extra added incentive, if helping just out the goodness of your heart isn’t enough, they’re giving away some trading cards. (If I get them, I’ll give them away, here. Promise.)
