Twitter placed a new "Quick Bar" on its iPhone app last Thursday, and as usual, when anything changes in the online world, there's a small and extremely loud group of hard-core users objecting to it.

The Quick Bar, appearing in version 3.3 of the iPhone app but not the iPad version yet, floats at the top of the Twitter timeline, displaying a rotating list of trends, including promoted trends (as you can see in our graphic here, but promoted trends only numbered about one out of ten trends shown). A finger swipe changes the trending subject to the next one.

Given a mocking name referring to both Twitter CEO Dick Costolo and possibly an anatomical reference at the same time, the "Dick-bar" is causing an uproar. It even has its own Twitter hashtag (#dickbar), and you can get your own giant version right here.

The Twitter iPhone app is currently receiving numerous negative votes on iTunes, currently garnering an average two-star rating for the latest version with 2173 users voting. But Twitter is not stubbornly letting users fester in their own frustration, like some organizations have done in the past (I'm looking at you, Digg). Twitter reacted, as evidenced by its communications guy Sean Garrett's tweet from Saturday night:

Sean Garret: Twitter submitted an update to Apple yesterday for our iPhone app. It fixes some bugs & makes it so the quickbar doesn't overlay on Tweets

Notice that Garrett is not saying Twitter's going to make it possible to disable that Quick Bar. Did Twitter go far enough, banishing the Quick Bar from tweets but not the timeline? Will this open the floodgates to lots of banner advertising on Twitter? Should we object to ads on Twitter? Let us know in the comments.

This calls for a poll! Let's vote for or against the Quick Bar right here and now:
