Twitter experimenting with longer posts

|By:, SA News Editor

Twitter's (TWTR) ironclad 140-character limit might be loosening up a bit: The microblogging platform is testing out a "Retweet with Comment" feature that would prevent the text of a retweeted post from counting against a reply's 140 characters.

Th effect of the format, which puts a retweeted post inside of a Twitter Card, is to give users more space to comment when both quoting and replying to a post. It's one of a long list of new features and product changes Twitter has toyed with as it tries to better appeal to those users bewildered by its traditional 140-character post streams.

Twitter is just two weeks removed from announcing COO's Ali Rowghani's resignation, a move that reportedly stemmed from product-related tensions. Ex-Google Maps chief Daniel Graf was hired in April to be Twitter's consumer products VP.
