I'll jump in on this - just to say I think this is down to a miscommunication with the blog.
I certainly hear you and the others in the team do too. We understand a lot of you feel the fact you can see the poll results means you feel it is pointless to vote - and that matches what people told us when I asked what reasons people have for not voting a couple month ago on the Q&A too.
It's not the one exclusive reason though, and there's more problems with polls than just hiding / showing - we want to understand those too :).
Apologies it wasn't clear - I'd be blown away if anyone hasn't seen the amount of times you all have asked about hiding results and the explanations for why you want it done - the crabs have been everywhere :P.
