What is Web 2.0?

[Robert J. Cordingley]

There have been some occasions recently when a particular technology or
solution we have been looking at was referred to as "Web 2.0".  Some
preliminary research on what is "Web 2.0" has only confused me some
more.  So (with Steve Guerin's blessing) I decided it would be useful to
poll the FRIAM group with a few questions in an attempt to clarify the
meaning of the term.

I hope to include a summary of the various thoughts and opinions in an
upcoming newsletter I put out.  I'll post a copy here too.  So, there
are only a few ground rules:

    * I won't mention names of contributors in anything I publish.
    * In responding, you are letting me quote you (anonymously) and
      letting me use the compiled responses, without copyright
      infringement.
    * Please try not to bury me with long epistles, material that is
      excessively technical or laced with large doses of jargon.
    * Please send your contributions directly to me at
      robert at cirrillian.com by September 15, 2008.

The newsletter (http://www.cirrillian.com/newsletters.html) is free and
comes out about 4 times a year.

So here are a few questions to get the gray matter going:

    * What was Web 1.0?
    * What is Web 2.0: a technology, a style of usage, a type of
      application, none of the above, all of the above?
    * What will follow?
    * Is there anything worth mentioning in between?
    * What can your share about your profession?

Thanks for your contributions!

  HTML, with or without all the dynamic content capabilities, served by
a web-server to a browser, primarily in a one-way information flow.
Yes, Web 1.0 included information flow from browser to web-site
(eCommerce, webmail, and webforums) but the duplex flow didn't have the
purpose of explicitly connecting the browser users or taking advantage
of multiple users at the same time.  The relationships were,
essentially, many to one.

  Web 1.0 that takes advantage of the distributed user base and duplex
communication to achieve emergent capability not possible through the
standard, simplex, server-browser model.  This implies some use of
active content and possibly applications served through the browser
(usually executed on the client's computer).  Web 2.0 is web-server
moderated many to many relationships.

  Web 3.0?  Seriously, the next step will be a peer-to-peer web.  This
will converge chat/IM, peer-to-peer file transfers, and
web-server/browser capabilities.  This will require new protocol
specifications and software that combine the various components.  None
of the existing mechanisms will provide all the capability.
Essentially, the browser will morph into a combined browser/server with
peer-to-peer capability and standard plug-ins (or APIs) that integrate
other applications such as chat/IM/VOIP.  One will browse the web,
still, but what one sees, hears, types and speaks will travel via other
users and will not be moderated by servers.  Security and privacy will
be interesting.

  Web 2.1 through 2.9 - basically variants on existing protocols and
standards that mash up the individual components of Web 3.0 until a
fully capable protocol/standard emerges.  Some of the in-between already
exists in the form of apps like Google: Earth/Sky - web but not web.

  I'm not a cracker, but I play one on TV?  I perform authorized,
adversary-based, system security assessments for defensive purposes.
