just an update...
The op is completely correct. This past day, pledges have "blown up" simply because a few here have been pushing people to the web site on the forums, facebook, reddit, etc.
Here is a breakdown of the result:
take notice of the % new visitors. There is a lot of people who haven't seen it yet, so it's not good to assume these moneybombs are even known about by a large amount of people.
My focus over the next few days will be to improve the share capability of the web site and also building up additional functionality that will encourage involvement. Anyone willing to help on some of the mundane tasks? Once i put in place some of these widgets and things, i'll need help from some people to get other web sites to pick them up.
