It's ok to abstain from voting if you don't feel confident about providing an estimate for SOME of the tasks. However if team members cannot provide any input on any of the stories then you have a bigger problem. > usually results in a shrug This is a problem. I'd suggest to repeat voting after having a conversation. And like I've said before - developers should try to commit themselves to deliver a chunk of work. It's hard to commit to random estimate that does not take your point of view into account. You could also try replacing story points with t-shirt sizes. If you cannot agree whether the story is 2 or 4 points, maybe it would be easier to agree between M or L. I am not a big fan of this method but I've seen teams for whom it worked better than story points.
