As with everything... the more you complain the more likely they are to listen. #Dickbar for instance, after 1day they made it less intrusive! Not what we wanted exactly but still a little helpful. Personally I'm waiting for TweetDeck to update
How much influence should users have in the development of updates to applications?
Keep things in mind on apps that do no listen to users enough:
Facebook for iPad (does not exsit)
Twitter App's "Dickbar"
Netflix for iPad
If enough users complain then they will update them.
I've seen netflix change their plans due to customer voice - maybe they just haven't gotten enough customer complaints to do the updates that you were looking for.
