The tags can be very frustrating at times.......I've learned over the years to care less & less about what # is hanging on my bag! I've heard that -- "I've already got a challenge" stuff a bunch of times. And then playing in tournaments, getting on a card with some top notch players.....& they've all got, ugly three digits tags while I've got the only decent one (and not for long).
And discdoh made a good point....tags should (obviously) be a singles thing.......I've been playing doubles (or even a 3-Man thing!) with someone wanting to play for tags, how the hell is that supposed to work?? I think in general Magic summed up the whole tag situation quite well.......
Oh and one more thing.......it is ridiculous (and it happens ALL the time), when a player doesn't have their tag with them! It's at home, it's wherever.....it's called a "bag tag" for a reason, why would you EVER have your tag anywhere other than on or in your bag.......
