Bonus XP weekends. Good or bad?

Bonus XP weekends. Most people liked the idea, but some didn't. Rafftank is talking about some negatives here. Yet I saw many positive blog entries back in March. So is it good for the game in a long run or not?

I don't know. I missed the excitement of preparation weeks for the first XP weekend, but from what I saw in other blogs it was fun. I'd love to be a part of it next time. I did logged in during that weekend and trained Summoning, Herblore, Smithing and Agility from 2.7 till 1.7 bonus. What I do know is that anticipation of the next XP weekend changed the way I train some skills. Especially Summoning: basically I am hoarding charms since March, waiting for the next XP weekend to spend them. Kind of scary how just one odd day could change the whole skill. And I have a suspicion that not only for me.
