I hope the two groups are able to work out their differences. I would love to see some of the strengths of io.js transfer into Node.js from both a technical and organizational perspective. The io.js project has been surprisingly thorough. So far they have kept on a consistent schedule of updates, provided excellent transparency regarding their team meetings and working groups, and they have been very responsive to feedback. I still use Node.js (with the harmony flag) for my production servers in hopes that there will be a merger soon but I may be in a dilemma if it doesn't happen within the next few months.
