Tomorrow is my sister’s last chance to collect money for her Relay for Life American Cancer Society fundraiser.

After a good fundraising day yesterday, I encouraged her to increase her goal from $200 to $1,000. See, I fully believe that, if media and networks are correctly leveraged, social currency can be converted to cash dollars for a good cause.

Since I’m more or less broke, I’m hoping that I can cash in some of my social currency to help out my amazing, brilliant, big-hearted little sister with her cancer research fundraising.

Story Time!

Over the past few months, my father has also been involved heavily in fundraising for Massey Cancer Center in Richmond, Virginia. Based in Virginia Commonwealth University’s med school, they focus on research and treatment and are one of the leading programs in the country.

Dad works at the Federal Reserve and has been tirelessly campaigning for this cause, putting on all kinds of events – luncheons, concerts, silent auctions. Pop also happens to be a triathelete, and he puts his excellent health and endurance toward cancer fundraising, as well. Recently he got my brother and Rachel’s (my sister’s) boyfriend to run a 10K with him for that very purpose.

Being a blogger, running isn’t really my strong suit (are you kidding me?). Another part of being a blogger, at least for now, is that I’m usually either flat broke, slow-leak broke, or straight-up-busted broke. The one thing I have that I can push toward cancer fundraising is my share of voice.

I broke down the math in my head the other day: I’ve got about 1,100 Twitter followers, a few hundred friends each on MySpace and Facebook, a blog with so-so traffic, publishing opportunities on other sites with excellent traffic (many thanks to Allen Stern of Center Networks!), and a long tail of friends and followers on sites such as Posterous, Plurk, Noovo, et cetera. Let’s be conservative and estimate that about 1,500 people pay attention to what I say.

If 10% of my network donates $5 (the minimum allowed donation) per person, that comes to $750. Plus, you have to account for those who are able to donate more. In a show of faith in my social graph, I told my little sister to increase her fundraising goal to $1,000.

Have I just set my baby sister up for a huge disappointment? Or will my social currency convert to real-live American dollars to help fund cancer research?

You decide.
