Classification (of internet sites/companies) on the mode of operations:
1st: info&services
Some sites are the extension of their operations in other fields.
Like news sites, which has reporters, journalists, editors etc which are only an extension into new medium(internet) to withhold their audience.
Ex: http://www.bbc.co.uk/ , Some sites like www.idlebrain.com for the regional (crazy) issues to reach globally dispersed audience. For these technical team is secondary.
information (products, appliances reviews etc) sites also fall in this category.
2nd:techie
Other classification is technically driven stream like google, yahoo, facebook, etc. for these technical team is primary. These use the extensive, unique features of internet to gain the consumers by services like Mail, blogs, social networkings etc. These companies are responsible for many major break through in the internet medium
And are dominating the web world
3rd:gen
sites not with primary aim to increase net traffic but to promote their product, access to customers, improve the customer relations through new medium. These mostly spend money only on developing their sites and advertising their products (many schools n colleges having a web portal can be categorized under this & most of the websites u developed so far too)
not that every site perfectly falls into a category. some are combination of two or more classes, like amazon.com is 30% of class techie n 70% class n our alumni-networking thing is 60% techie n 30% info&services n 10% gen)
and now we also need some units to measure the standards too based on a site`s market, traffic etc. for example in the stream of social networking, i would rate facebook 9/10, orkut 5.5/10
