Twitter Effectively Expanding Tweet Limit On September 19

Twitter isn't significantly increasing its tweet character limit like had once been reported, but it is going to exempt most attachments from the limit, thereby effectively increasing the character limit. On September 19, attachments like images, polls, videos, and other tweets will not bring down your available characters.

Given much of Twitter runs on tweets that embed other pieces of content, this update will help many users and it's the sort of change people have been asking for.

Usernames included at the beginning of tweets also won't count against the limit.
