What's Facebook Got Up Its Sleeve?

NEW YORK (TheStreet) -- Facebook's (FB) will hold a major press event at its headquarters tomorrow, and the world will be watching. This could be a huge event, with a capital H.

There's been plenty of speculation about what the social networker has up its sleeve. Facebook often saves its big announcements for the company's F8 developer conference, so this marks a departure from the company's usual strategy.

I suspect CEO Mark Zuckerberg and his team, now that Facebook is public, are trying to one up the tech industry, which is perfectly normal. It happens all the time. Companies try to schedule events around Apple (AAPL) product launches to gain exposure. It works, but not to the degree many would like. Facebook is different because it's a product more than 1 billion people use, so there's going to be a considerable attention focused on this event.

On to the event itself. What will Facebook announce? Zuckerberg has already talked about building a social search engine. "Search is interesting," he said at a tech conference back in September. "We do on the order of a billion inquiries a day, and we're not trying." He went on to say that at some point Facebook would do something with search, but didn't get into specifics.
