Nodejitsu runs npmjs.org as a free service to the community. The rapid growth of Node.js (and thus Node.js package usage) means that this service costs significantly more than it once did. This cost comes in both dollars and resources.
I feel that we, as Node.js developers, owe the npm project almost as much as we owe the Node.js project itself. Node.js without npm would be cool, but it would be too hard to use.
Nodejitsu has launched a campaign to solicit donations from the community at both the individual and corporate level.
Please consider donating to the project personally or through your employer.
