Many of these trends have been evolving for some time now and will surely receive attention in 2010.

Flex & Flash:

Most websites now integrate flash/flex to some degree while standalone applications are also on the rise. The technology is being used for way more than web animation.

Micro-blogging/Messaging/Status Updates:

Twitter made famous the short comments/status updates which are now being widely used in many websites, most notably in Facebook, and are becoming more prevalent in emerging startups as well.

Online reputations (individuals and businesses):

The best example of online reputations is demonstrated in EBay’s seller reputation or Yelp’s business reviews.  Online reputations are beginning to hold more value and services intended to support these reputations are beginning to spring up as well.

Cloud Computing:

The marketing effort on the cloud computing front seems to have increased substantially. The idea (and service) isn’t new but the quantity of companies and startups setting up their own clouds as a business model is greatly increasing.

Social Media:

The buzz these days is “social” and it seems most new ideas find a better way to harness social interactions via the web. There is consolidation going on right now where management services are being created to help individuals navigate through social sites more effectively. Social sites will continue to spring up and evolve while management aggregation sites will follow the trend. Newest example is Google Buzz.

Geolocation:

Many web companies and mobile developers are beginning to make a hard push for geolocation which can have a direct impact on social networks, advertisers, and especially for small and local businesses. Companies pursuing a geolocation services include Google, Gowalla, Apple, Twitter, and many more.

Video Advertising:

Many video sites, not just YouTube, are implementing advertising features where users will have to view an ad while watching a video. By exposing users to these ads, advertisers are able to build advertising channels similar to that of television.

Search:

Microsoft’s Bing will continue to take greater market share from Google.

Mobile:

Android will become a household name. Mobile marketing initiatives will continue to increase. Access to the internet via mobile devices will skyrocket resulting in websites catering to their mobile traffic.

Real-Time:

Websites will continue to implement real-time features such as Google and their Real-Time search. Mobile providers and developers stand to make great strides in this arena.

Content Creation, Aggregation, and Management:

As more and more content is being created through blogs, microblogging, discussions, and online comments there is a growing need to manage this data on a large scale.  The information contained within the content will be attractive to marketers, product developers, and startups in general. 2010 will continue to see services and ideas intended to address content.

Analytics and Intelligence:

With the explosion of data and content creation there is a growing need for expertise to extract relevant information. Many companies, such as Twitter, have a need to understand their users and trends within their communities. There will be more in-house analysis and analytics teams as well as independent service providers devoted to mining all this data.
