With WotLK, the new achievements are pretty cool, but the trend for telling your guildees "Gratz man! You just caught 25 fish!" is pretty annoying.
Its really no big deal, but you always seem like an ass if you are the only one not being a supportive guildee. Some addon that detected guild and party achievements nd auto congradulated them would be pretty cool. And if you took it really far, had some witty phrase to go with it based on the type of achievement. I.E. So-and-so just go the [Explored Wherever] Achievement, and the addon saw "explored" and said "These boots are made for walkin, and thats just what you did! Grats!" That would be a nice auto response so I could go on with my daily questing.
Laziness for the win.
And for the lazy and/or extremely user friendly coder, allow users to put in thier own quips so you don't have to come up with them yourself!
