Impact of URL shorteners in Twitter feeds

[Urbanfox]

Hello,

Will use of URL shorteners [bit.ly/tiny.cc or equivalent] in Twitter feeds impact the rankings of a target pages?

As I understand it Twiitter links are automatically generated as nofollows so I am assuming the published link is irrelevant.

Is this still the case?

If we do continue to use URL shortereners should we look at branded URL-shorteners to provide link context?

Thanks.

Aside from the Twitter feed factor, as far as I'm aware there is some issue where only some shorteners pass link juice while others don't. I can't remember where I got that from so I did a search to see and found this (not sure of its credibility though): http://www.kensfi.com/how-url-shorteners-pass-link-juice/

There's some links from SE Land here though which seem to be saying all is well  http://searchengineland.com/twitter-gets-its-own-url-shortener-to-stop-scams-37676

That only really half answers the Q, but interesting none the less I think
