I understand the desire for the "lucky" tag, but ultimately I think it will just add noise since most of use will be perceived as lucky at some time or another by other players.
I'm hoping/crossing my fingers that at some point something interesting is going to be done with the tags. There was mention in one of the threads in the early days of "tag clouds" which, using my rating tags at the moment as an example could produce something like this:
My tags are currently as follows:
friendly (5)
talkative (1)
quick (3)
trustworthy (1)
brave (1)
good strategy (3)
helpful (2)
silent (1)
balanced play (1)

making tags useful thread for discussion of this ...]
