I was disappointed that the game devs discontinued the Junior/Veteran/Master Debugger and Junior/Veteran/Master Consultant achievements. I had at least a dozen ideas implemented during my tenure as a player, and I still enjoy and continue to point out bugs and offer suggestions to improve the game.
While it's great to see one's name listed as a co-author of a scientific paper, I am guessing that to a newer player, that's not so important. We have a retention problem with new players, and I think that's because they're not receiving anything for their efforts.
I suggest not only bringing the old achievements out of retirement, but creating many new ones that can be easily earned and liberally distributed. It would also be good to have a section of the site similar to the leaderboard pages, listing "new achievements earned this week by players" or something similar. We like to see our names in print.
This ties into the idea offered by infjamc to create a new Achievement for creating a "scientifically valid" solution. See https://fold.it/portal/node/2011214 for that discussion.
