Presidential campaigns duke it out with their software apps for volunteers

The Obama presidential campaign is debuting its latest online campaign organizing tool for the 2012 election, one that is expected to be use by volunteers across the country to connect with voters.

The Wall Street Journal had a report on the tool -- called Dashboard -- that the Obama campaign is unveiling today. President Obama ran an aggressive online campaign back in 2008. Expect more online blitzes this year.

Meanwhile, Mashable reports Mitt Romney has his own online social network for volunteers, called MyMitt.

I'd love to hear from volunteers in Maryland who are using these online tools to help these campaigns with organization. Are they good and effective?
