The Twitter Charity Challengeended on 12/31.  Here are some of the accomplishments:

• $508 raised for charity by people following @mvolpe, plus I added $50 since Twitter did an account cleanup and dropped my followers by 100 during the month
• 6 other people joined the fun (thanks @corbett3000, @jessieX, @pmhesse, @SeanDaily, @JordanAyan, @dankeldsen) adding to the total raised and the number of people that heard about our causes

Overall it was a lot of fun and I'm glad I did it.  I actually don't think doing the challenge increased the number of people that were following me - I gained 1,050 followers in November... about the same amount as in December with the challenge.

I did learn a few things.  Some things I would do differently next time are:

• Start earlier so more people can join in and still have time to make a difference - and solicit friends to join before I publicly announced it.
• Use a wiki or public document for everyone to join and track their own donations.  There is no reason the Google Spreadsheet I used could not have been edited by lots of people and been a stacked chart to show the total raised for all charities.

Thanks everyone for your participation and help!
