Several others (including myself) are inclined to agree. The current draft reads:
Welcome, {{PAGENAME}}! We noticed that you placed a vote on [[{{{1}}}]]. Participation in the community is encouraged, of course, but your status as a brand new user means that your vote ''might not'' be counted. Voting on Wikipedia is meant to measure community concensus, and should not necessarily not be taken as literal voting. Please understand that this is a common practice on Wikipedia, and that it is necessary to prevent deliberate "loading" of our votes. However, we encourage you to make further contributions to Wikipedia and to become a valuable member of the community.
It's being discussed at http://en.wikipedia.org/wiki/Wikipedia:Administrators%27_noticeboard#Voting_....

I agree that it should be kept short, but I'm also of the opinion that it should include text to the effect that "votes" are not votes per se, and may be ignored for no other reason than the fact that they may be considered invalid for purposes of gaining a community consensus. A bunch of people whose only connection with Wikipedia is a VfD, and who will likely never have anything to do with Wikipedia again aside from that VfD and, perhaps, some vadalism, is not someone whose "vote" is particularly valuable in a test of community consensus.
Maybe that's just me, though.
