Comment packt isn't much more than a vanity press (Score 1) 53
one of their recruiters approached me last year to write a book on numpy. which was curious to me since while i've used it (and posted some very minor public code using it), i'm not a contributor, nor involved in the community in any way.
some googling led to some fairly consistent stories:
very little editing work
very low sales (rep told me 1000 copies would be considered successful for a sequel)
don't expect more than your initial front (~$3500, which isn't even a front; they pay it out over the different chapters you submit)
if they can they get multiple authors writing in the same category at the same time (which means you're basically competing against your own publisher)
needless to say: didn't want to sign my name to anything like that...
