Surprise, surprise. People use Facebook all day long, whether they’re working or not.

That’s one of the findings in the debut edition of State of Apps: Software, Games and Web report from Wakoopa, which tracks more than 75,000 heavy computer users and the more than 200,000 applications they have installed. Pearson is also a sponsor of the report, which tracked usage in the first quarter.

Wakoopa users have agreed to let the company track their application usage. The interesting results include these facts: peak usage for social networks is 9 pm to 10 pm, but Facebook usage happens consistently throughout the day. Across all web apps, the peak time is 4 pm to 5 pm.

Other results:

– Twitter continued its growth spike throughout the entire first quarter of 2009 with a heavy increase in March. Tweetdeck ranked first among users who posted updates to Twitter via desktop applications, with Twhirl a close second.

– The most popular new app on the Mac is Destroy Twitter.

– The most popular new apps on Windows are the games Burnout Paradise and Mirror’s Edge.

– Windows Live Hotmail and Symbaloo were the fastest gainers among web apps, while Google Friend Connect and Veoh showed the greatest decline.

– Google Chrome now commands 15 percent market share among browsers. The Opera browser has its highest adoption in Europe, while Firefox is the dominant browser of choice worldwide for Wakoopa users.
