There is a lot of hype surrounding the real-time web, and much of the feeding frenzy reminds me of the RSS space four years ago — though there is a lot of potential, there is also a lot of noise. How do you navigate through it all and which developments should you be paying attention to? What are the emerging trends for companies and entrepreneurs to watch for? Here are four real-time web trends that I’m tracking.

1. Real-Time Collaboration is Ripening

Companies that are more efficient have an advantage whether within their walls or with their customers. Imagine being able to make real-time changes with your colleague in another city and graphic designer at your local Kinko’s to finalize a presentation and print it hours before your meeting. Or working with your manufacturer in Nanjing, China on changes to your new BBQ grill design and seeing if it’s possible in real-time. Or game developers in Korea and Dallas story boarding a new video game concept in a new real-time game development application. There is massive potential for real-time collaboration across almost every discipline, and I believe there are an incredible amount of exciting possibilities here.

2. Real-Time Analytics Will Be Hot

Waze, which is a crowdsourced mobile map and traffic information service, is effective in Israel where it initially launched and needed just 0.5% of the population to become a reliable service. It recently launched in the United States, and will be challenged to reach critical mass in its target markets for its product to be useful to end users, who provide the real-time data that is uses. While Waze is not necessarily an analytics application — it’s a real-time information app (though it does analyze the data it receives in real-time to expose traffic patterns, accidents, and speed traps to users), it is an example of necessary tipping points for analytics to be relevant.

Once you have these real-time data sets, so many fields will be able to become more accurate and relevant in their decision-making processes. What type of real-time data would you like access to?

3. Real-Time Search is Looking Up

Here’s an example: Let’s say you’re wondering if you should you go see Depeche Mode in concert or if they are too old now to put on a good show. What are people saying about their concert from the evening before? If your search allows you to narrow your focus by date to make sure you’re getting info only from last night’s show, exclude all messages under 10 characters to filter out irrelevant information, and those from their home area of Basildon, Essex UK to rule out biases, you should be able to get a clear picture of what people think.

For the larger players, it will be a golden opportunity to capitalize on more event-driven ad dollars. Imagine the euphoria during the World Cup or Superbowl and all the tweets and messages surrounding these events. Now imagine the highly targeted ads that could be displayed to these users selling them championship videos or t-shirts at the height of their emotions. I’m still amazed by the uncanny targeting of ads within Gmail so it should be a short step for Google and other major advertising companies to be able to implement targeted ads across real-time streams.

4. Real-Time Ecommerce is Coming
