Web 2.0 refers to the more interactive, collaborative internet that emerged in the early 2000's. It describes websites and services that let users create, share, and engage with digital content and communities. Unlike the original Web 1.0's static pages, Web 2.0 allows participation. People can upload videos to YouTube, post social media updates, edit wiki articles, comment on blogs, and more.
Some main features of Web 2.0 include:
- Social networking sites like Facebook and Instagram
- Blogs and wikis
- Video/photo-sharing platforms like YouTube and TikTok
- Review sites like Yelp and TripAdvisor
- Live messaging and chat apps
- Creative tools that let anyone make websites or blogs
On Web 2.0, visitors become contributors. Users provide content and data that add value as they use an app or platform. This makes websites feel more dynamic, social, and personalized. With user participation at its core, Web 2.0 gave rise to community-driven sites, user-generated content, viral memes, two-way conversations between brands and audiences, and more. It made the internet not just a place to consume but a place to create, share, and connect.
Characteristics of Web 2.0
Unlike old static websites, Web 2.0 sites are interactive and encourage users to participate actively. Some main ways users can contribute:
- Comment on blog posts, news articles, and other content
- Create user accounts and profiles
- Upload their photos, videos, writing, etc.
By making participation easy and engaging, Web 2.0 sites feel more:
- Social - With user profiles, commenting, messaging
- Dynamic - With constantly updated, user-created content
- Personalized - With customized feeds and preferences
Other Web 2.0 features include:
- Social media platforms
- Blogging and website builders
- Tagging and organizing content with labels
- “Like” and reaction buttons
- Bookmarking favorite sites and sharing collections
The goal is to get users to add value by posting, customizing, reviewing, tagging, uploading, and sharing. This user-generated content and data is core to Web 2.0.
Some sites even require participation and contributions as a condition for access. Overall, Web 2.0 makes the internet not just a place to read and watch but also create, connect, and participate.
The key features of Web 2.0 include:
- Folksonomy - Users collectively tag and categorize content, which helps organize information and aids searchability.
- Rich user experience - Dynamic, interactive content responds to user input. For example, clicking an image enlarges it.
- User participation - Users contribute reviews, comments, and their own content through wikis, posts, uploads, etc. There is two-way sharing between sites and users.
- Software as a service (SaaS) - Sites have APIs so other services, apps, and mashups can access or share their content.
- Mass participation - Web 2.0 opened the internet up to participation from all types of users beyond just tech experts. This led to rapid growth.
In summary, Web 2.0 sites encourage participation, sharing, interactivity, and collaboration at scale. Users are contributors instead of just passive viewers of content. The value comes from the engagement between real-world people creating, customizing, remixing, and distributing digital content and ideas.
