Most of the people related to IT or social internet are (more then remotely) familiar with the concepts of Web 2.0 and SOA. The former has more cultural connotations with some technical concepts embedded,  while the latter focuses on enterprise software architectures and only on technology. Still both of those concepts have been (almost) overused during the last five years. There have been many discussions on Web 2.0 and it’s social impacts. Also SOA is a widely discussed topic with some good analysis on how it can improve an enterprise architecture in a company. Discussions on the relations between SOA and Web 2.0 and how they are related are also widely available. John Hagel has a nice summary of those discussions with a comment:

“When you talk to SOA proponents today, you will hear a lot about connecting applications and databases, but not a lot about connecting people together and helping to support their interactions with each other.  In contrast, Web 2.0 advocates put a lot more emphasis on the opportunity to connect people together and to support their collaborative efforts.  Web 2.0 certainly also addresses issues of connecting applications and data, but Web 2.0 is distinctive in the social dimension that it explicitly addresses.”
