<P> Travel 2.0 refers a model of Web 2.0 on tourism industries which provided virtual travel communities . Travel 2.0 model allow user to create their own contents and exchange their words through globally interactive features on websites . The users also can contribute their experiences, images and suggestions regarding their trips on online travel communities . For example, TripAdvisor is an online travel community which enables user to rate and share autonomously their reviews and feedbacks on hotels and tourist destinations . Non pre-associate users can interact socially and discuss through discussion forums on Tripadvior . Social media, especially Travel 2.0 website, plays a crucial role in decision - making behaviours of travellers . The user - generated contents on social media tools have a significant impact on travellers' choices and organisation preferences . The travel 2.0 emerged a radical change in receiving information methods of travellers from business - to - customer marketing into peer - to - peer reviews . The user - generated contents become a vital tool for helping a number of travellers manage their international travels for the first time visiting . The travellers tend to trust and rely on peer - to - peer reviews and virtual communications on social media rather than the information provided by travel supplier . In addition, An autonomous review feature on social media would help traveller reduce risks and uncertainties before purchasing stages . Social media is also a channel for customer complaints and negative feedbacks which can damage images of organisations and destinations . For example, a majority of UK travellers read customer reviews before booking hotels and the bookings of hotels receiving negative feedbacks would be refrained by half of customers . Therefore, the organisations should develop strategic plans to handle and manage the negative feedbacks on social media . Although the user - generated content and rating system on social media are out of business controls, the businesses can monitor those conversations and participate in communities to enhance a customer loyalty and maintain customer relationships . </P> <P> Web 2.0 could allow for more collaborative education . For example, blogs give students a public space to interact with one another and the content of the class . Some studies suggest that Web 2.0 can increase the public's understanding of science, which could improve governments' policy decisions . A 2012 study by researchers at the University of Wisconsin - Madison notes that "...the internet could be a crucial tool in increasing the general public's level of science literacy . This increase could then lead to better communication between researchers and the public, more substantive discussion, and more informed policy decision ." </P> <P> Ajax has prompted the development of Web sites that mimic desktop applications, such as word processing, the spreadsheet, and slide - show presentation . WYSIWYG wiki and blogging sites replicate many features of PC authoring applications . Several browser - based services have emerged, including EyeOS and YouOS. (No longer active .) Although named operating systems, many of these services are application platforms . They mimic the user experience of desktop operating - systems, offering features and applications similar to a PC environment, and are able to run within any modern browser . However, these so - called "operating systems" do not directly control the hardware on the client's computer . Numerous web - based application services appeared during the dot - com bubble of 1997--2001 and then vanished, having failed to gain a critical mass of customers . </P> <P> Many regard syndication of site content as a Web 2.0 feature . Syndication uses standardized protocols to permit end - users to make use of a site's data in another context (such as another Web site, a browser plugin, or a separate desktop application). Protocols permitting syndication include RSS (really simple syndication, also known as Web syndication), RDF (as in RSS 1.1), and Atom, all of which are XML - based formats . Observers have started to refer to these technologies as Web feeds . Specialized protocols such as FOAF and XFN (both for social networking) extend the functionality of sites and permit end - users to interact without centralized Web sites . </P>
