Web 2.0 - what is it?

It describes almost any site, service or technology that promotes sharing and collaboration online.

Google is to Web 2.0 what Netscape was to Web 1.0

  •  Web 1.0 = Read only, static data
  • Web 2.0 = Read write, dynamic data (collaboration)
  • Web 3.0 = read, write and relate 

Characteristics

  • Network as platform - delivering applications entirely through a browser
  • Users own and control the data and when and where to receive information
  • Allows user participation (blogs, wikis)
  • Social networking (discussion groups)
  • Richer, interactive user-friendly interface

Some Web 2.0 Tools

Blogs are online journals. http://Blogger.com is one of several  websites that you can use to create and host your blog for free.

 

Wikis are simple web pages that a group of people can edit together. Wikis are great for collaborating on a project or presentation. You can set up a free wiki at PBWiki.com

 

Youtube is a very popular videosharing website. Upload your public service announcements or educational videos and reach millions of people with your message. This site is popular amongst state and federal government agencies, politicians, academic institutions,  hospitals, newsmedia, etc.

 

Use flickr or Picasso to organize, share, print your photos.

 

Use del.icio.us to keep all your bookmarks in one location.

  • Research - Writing an article? Researching an industry? Slaving away on your dissertation? Use del.icio.us to keep track of all the source materials and commentary that you find online.
  • Wishlist - Go to any commerce site, find what you like, save it to del.icio.us and tag it as wishlist. Then you can tell people to check out your wishlist bookmarks by giving them a link to http://del.icio.us/username/wishlist .
  • Podcast - Want to hear some great podcasts? Visit the mp3+podcast tag combination and start listening. Are you a podcaster? Start posting your mp3 files to del.icio.us and we will create an RSS feed for you.
  •  Collaboration - Friends, coworkers, and other groups can use a shared account, special tag, or their del.icio.us networks to collect and organize bookmarks that are relevant -- and useful -- to the entire group.

    Google Docs 

  • Import your existing documents and spreadsheets, or create new ones from scratch.

    What Next? Web 3.0

    Terminology:

    A place where machines can read Web pages much as humans read them. A place where search engines and software agents can better troll the Net and find what they want.
