Review of edelmans.com

This page offers lot of information. There is lot of information about the company and the Expertise section is very useful and interesting. It gives you an insight to the industry. This page could give you personal identity if you are interested in the subject of PR and Marketing. However if you are not interested in those things it would probably not.
Intergration and social interaction is in a way a part of the Expertise section because it is mostly about the Company's work and approch. Reading about their approch to things and issues and their work you could feel a sence of belonging. It could also be a basis for conversation and other social interactions.
The site is entertaining. It is fun to look at the design portfolio for example.
As said before this website offers a lot of informations and it could be confusing if you don't know exactly what you are looking for. So I think you wouldn't spend much time on it unless you are looking for something specific.
I think the main reason for this site's existence is to give information about the company and that it does well.
