Web 2.0 technologies

What is this blog about and how I’m going to approach the subject?

Hi! My name is Kaarle Glad and I’m first year Master’s student in Tampere University of Technology. When I received the information about my topic for my blog section, I started thinking the way I’m going to approach the subject. I’m new to blogging as this is my first blog post ever. I actually don’t even read blogs so often. I think that videos and audio are great ways to distribute and receive information. So I will add videos for each subheading in this blog. Videos will give definitions and examples on the topic and then there will be some deeper knowledge retrieved from various sources I find interesting. I hope you find my blog post interesting and feel free to comment on it!

What is Web 2.0?

If Web 1.0 is described as “passive”, Web 2.0 can be described as “interactive”. Common for Web 1.0 was that users mostly just read static web pages. Web 2.0 is based on users creating and contributing content and easily search content desired. Web 2.0 can be described as collection of technologies, business strategies and social trends. Developers can easily create new Web applications that utilize data, information and services available on the internet. The collaborative nature of Web 2.0 technologies leads to establishing social networks with common interests, gathering collective information and collaborative content creation and modification. (Gupta 2012)

Tim O’Reilly and Dale Dougherty popularized the concept of Web 2.0 in Web 2.0 Conference in 2004.

Patrick Schwerdtfeger defines Web 2.0 and social media in this video.

Andrew McAfee discusses about what is Web 2.0 and the difference between Web 2.0 and Enterprise 2.0.

Web 2.0 technologies


Anyone can create blog pages to post their ideas and thoughts on subject they choose. Usually blogs contain text, images, videos and links. Other users can comment on blog posts.

RSS (Really simple syndication)

RSS is a family of Web feed formats used for organizing content from blogs or Web pages. It is a XML file that contains information items and links to the sources of information. RSS notifies users about updates on blogs or Web sites they have subscribed.


Wikis are Web-based collaborative-authoring system creating and editing content. Users can create, edit and revise articles through Web browser. Wiki sites are known for simple site structure and navigation. Linking one page to another is easy. Wikis have also a built-in search feature that allows users to find a topic with associated keywords.


Mashup is a Web page or site that combines information and services from multiple sources on the Web. One of the most important feature of Web 2.0 is the opportunity to create a mashup rather than code an application from the scratch. Mostly used mashups are mapping mashups, other categories are search, mobile, messaging, sports, shopping and movies.

Tags, folksonomy, and tag clouds

Tags are keywords that makes content searching easier. Folksonomy is described as user-created taxonomies of information. Using tags or label, users can categorize content they find or post online. It doesn’t have a controlled vocabulary. Tag cloud is a list of content tags. Lists are presented visually and differentiates between tag’s popularity levels.


Podcasts are digital audio or video files that can be subscribed through podcast feeds. Especially handy way of retrieving information while traveling.

Social networks

Essential for social networks is that individuals or groups have profiles in the network. Profile can be linked between networks. Sharing information, audio, video and documents are key elements of social networks.

Web 2.0 development tools

Developers use three principle development approaches to create Web 2.0 applications: Asynchronous JavaScript and XML (AJAX), Flex, and the Google Web Toolkit. Creating Web applications with AJAX enriches the user interface, making it highly interactive and responsive. It combines technologies XHTML, HTML, CSS, JavaScript and XML. Adobe Flex is based on Flash and is an application development solution. It enhances the user experience by increasing user activity with the application and has a data visualization feature. Google Web Toolkit (GWT) is an open source Java development framework. GWT overcomes the limitation of writing AJAX applications using mix of technologies, such as Java, JavaScipt and HTML. (Murugesan 2007, Gupta 2012)

This video introduces an example on how Web 2.0 technologies can be integrated into learning processes improving student engagement, communication and collaboration. Video also shows how to use those technologies.
