If I were them, I'd say something like:

"io.js is an api-compatible alternative to the node.js runtime, including support for the npm ecosystem, that aims to release faster than the node.js release cycle and move according to a community-driven open governance model."

Given the tremendous volume of packages released to npm, the current one-liner initially just doesn't convey much information. In context of the comments here, it all parses perfectly, but I was one of many who needed this context to understand the (apparent) goals of the project.
