Agreed, even if the page says "WE NEVER POST WITHOUT YOUR PERMISSION", the twitter auth page says that it asks for authorization to do so.

I won't link my twitter account to an empty page on the internet that can tweet for me, read my timeline, update my profile (!) and follow new people (seriously?).

Great point! We just updated the copy to reflect what you can do with the app. We'll update it more permanently to reflect your suggestions in the next few hours. Thanks again!

Great suggestion -- we'll work on our landing page. If you log in with twitter you can post a poll from our app, and we'll track all votes for you. Thanks!
