Quick summary for those out of the loop about GCI: We define bite-sized programming tasks, Google comes in and finds people who want to do them, we mentor them and get new participating members in the community.
Friday is the first deadline for GCI, it is the day where we decide as a community whether there is enough interest to continue. Right now we are seriously lacking. If you're interested in getting some more people to help out with D8, if you're feeling a little burned out please take 10 minutes and write up an idea or just comment on someone else's idea and offer to help mentor. 10 minutes and D8 will have a whole new crop of skills friends to help out.
