Web 2.0 is the dominant 'meme' in web development and design discussion right now. Like a lot of catchphrases associated with the web it could be dismissed as dressing something old in something new. It also could be seen as one of those terms that means whatever the user wants it to mean. There is a healthy amount of cynicism of the band-wagon-jumping happening at the moment. Like all buzzwords and movements, there is a certain amount of judgement required. Some of the tools involved in Web 2.0 are truly useful and are remoulding the web, others seem to be a hodge-podge of ideas that have very limited use.
There is however a core set of features that are at the centre of the Web 2.0 buzz. The one I want to talk about is that affecting design, namely the effect of user interaction. In the coming week I will follow this post with words on design and adopting Web 2.0 tools in the academic arena.
In the past IAs and others who design websites have been used to carefully laying out the available information, weighing up the needs of users and the strategies of the business and trying to come up with a structure that is user-focussed and also caters to the needs of the business. For examaple, high school students want to find out about the University, the University wants them to apply to study here. The language and structure used to communicate through the website is aimed at the high school students but the actual information comes from the organisation.
Sites designed like this are pretty simple, they deliver information and may provide a low level of interactivity, such as forms and registration. What we are seeing now is a proliferation of sites that provide more than information. They provide functionality, they allow users to create and organise their own content, they provide channels for further investigation and allow themselves to be built upon. A simple example is the use of RSS feeds on sites other than blogs.
The RSS feed took off with the escalation of blog use. Too much information being produced, not enough time to keep track of it. RSS feeds enable the constant monitoring of blogs without actually having to visit the sites. Bookmarks for high-content sites like blogs become redundant. The content is pushed to the user, who has initiated it by activating a 'pull' through their news reader.
Now the RSS feed offers more than a system of tracking content production. Deli.cio.us enables feeds of other's bookmarks, or a feed from a certain tag. For the user this acts as a lever to further investigate, to build upon the bookmark system itself. The feed keeps track of other user's interaction with the site, not the content the site provides.
Feeds from Flickr and other tag-based social applications work in the same way. Users generate content of sorts but it is their interaction with the application that provides interest to others.
An example: I live in Newtown and like to take photos of Newtown and post them on Flickr. I have an RSS feed from the Newtown tag. Any time anyone posts a photo with this tag I know about it. I look at the photos but I also interact with Flickr by posting my own photos, adding contacts, commenting on the photos of others and adding my photos to groups. It's a loose form of social interaction.
Another: I have an RSS feed from the del.icio.us tag 'IA'. Anytime anyone bookmarks something and tags it 'IA' I get notified. I can then investigate the bookmarks of others and find more material for research. Sure, I'm looking for content but I'm not browsing for it. The interactions of others are providing me with a different path to it. It's less labour intensive and allows me to tap into the thoughts of others in terms of classification. We don't all call things by the same name and sometimes you're sprung with some pleasant surprises.
As I mentioned, the idea of browsing the web is becoming redundant. The web has always allowed you to move sidewards, this is the beauty of it, but new tools associated with Web 2.0 allow for a more refined web using experience. It allows for the consumption of more content with less effort. The beauty of this is that a lot of it is user generated. You're not bound by the structure of sites and their connections with others sites (through links etc). You create your own connections and with luck this can lead to sideways movement of thought, building upon the oringial 'sideways' thought that the web allowed. Connection between information is sped up through the interaction of general web users with these new tools.
The really simple thing about this interaction is that it's informed by offline actions. Many web 2.0 tools fulfil purposes that have their roots in things we do in everyday life. They just move it online and thus are able to use the lateral nature of the web.
Sure, we've been able to interact with the web for a while, online banking for instance. These 'web 1.0' interactions were more streamlined, they had a beginning and an end. They had a defined purpose and had no larger context than this single purpose. Web 2.0 interaction is not pre-defined. There is a basic premise but they are able to be built upon. In the words of others they allow for mash-ups, they ask to be hacked, not in a technical sense but in a sense of what they can be used for. Of course, developers have always written ad-ons for software. Now the 'mashing' is happening with content.
Web 2.0 moved beyond the hard core of web enthusiasts long ago. Two mainstream examples: The Washington Post encourages 'mash-ups' of its content and UPenn library provides a bookmarking service that enables users to share their bookmarks using tags. It's high time we took a good hard look at it.
