OK, class, it’s time to review the latest studies, which seem to give us a pretty clear picture of the online world.

1. Internet usage is peaking.
2. Social networking sites are on the rise while social sites with a single focus, like Flickr or Blogger, are not (except YouTube).
3. The blogging audience is peaking.
4. Video watching and sharing continue to grow, especially among young adults.

These are some of the findings from reports this week by Forrester Research, Universal McCann and the Pew Internet and American Life Project. What they tell us is that our media habits have somewhat stabilized. While Internet usage doubled in the past five years, TV viewing habits haven’t really changed, according to Forrester. People still spend more time watching TV than online. Radio, newspapers and magazines have been the victims of Internet growth.

So what does this mean for small businesses and professionals? They’d better be thinking about Nos. 2 and 4 and what strategies they can use for these worlds. Social networks and video-sharing sites are the hot zones.

It also confirms my experience. The best way to draw people to your blog or company Web site is through social media. Otherwise, people won’t come looking for you.
