I’ll bet old, high-karma users who have not logged into LW2 yet would be interested if you sent them an announcement email about this. (Actually, I would guess that a lot of old users would appreciate a LW2 announcement email, but tailoring it so high-karma users are told karma=power would probably boost clickthroughs for that subgroup and maybe reactivate old contributors. Depending on how snobby you were feeling, you could restrict your announcement email depending on the user’s upvotes recieved to downvote received ratio.)
