Nearly everywhere you look around the Austin Convention Center during South By Southwest, you'll see eyes glued to a smartphone or a computer screen.
Many of those people probably are staring at the popular microblogging service called Twitter.
Williams will talk about the future of social media and where Twitter will go from here.
There is also some online buzz on whether Twitter will debut its advertising platform on how to remain financially solvent.
A recent study just released by Web security firm Barracuda said only 27 percent of Twitter's 50 million users are active on the site.
That means 73 percent of those who have signed up for Twitter have only sent messages 10 times on the service.
Many people said the service has gone from a social platform to a news feed, but those who stand by Twitter said it helps them immensely in their day-to-day work.
"It has turned into less witty comments and less social interaction, which I think it's OK," said Lauren Shannon, an active Twitter user and attendee of the SXSW Interactive Festival. "I think Facebook has taken the place of more social interaction."
Just how Williams and Twitter plan to keep up with the rest of the social media crowd will be unveiled at the Austin Convention Center at 2 p.m. Monday.
