The hype around an announcement by Twitter founder Ev Williams at South by South West (SxSW) was that the company was going to announce it's plans for monetizing it's service but well all was said and done the actual announcement was viewed as underwhelming, with some attendees bailing before the key-note address was over.
"What Mr. Williams did announce is a Twitter expansion called @Anywhere. It allows users to log into other websites using their Twitter accounts, so they can tweet a link to something interesting without having to actually go to the Twitter site. Those third-party sites will highlight names and businesses that use Twitter and, when the mouse scrolls over them, a window pops up showing the user's account and latest activity there.
“Imagine being able to follow a New York Times journalist directly from her byline, tweet about a video without leaving YouTube, and discover new Twitter accounts while visiting the Yahoo ! home page,” the blog post announcing the change said."
As an avid user and Twitter fanboy, I don't really care how they make money as long as they are able to keep the doors open without selling their souls and invading my screen space.
