No, it IS a bad thing. What you get (and what happens on SO) is that certain people will post something, anything, to new posts so they have the first comment. They then spend the next five minutes gradually expanding their answer either based on their own knowledge or worse of all, by cherry picking info from other peoples answers.
This is certainly not the case with every answer, and it it may be more prevalent under some tags than others. However it happens enough that I've become fed-up of crafting well thought out replies just to see them copy+pasted, with some minor word changes, into answers from first-posters.
