Good examples of sticky sites are portals which are simply sites that act as a stepping stone or hub and point you to other sites. The portals may point to other sites of simular interests or not. Most businesses will need to balance the need for quick information and a painless way to purchase products without wasting the customer's time. Sticky can be a good thing if you have lots of bandwidth, dedicated servers and a message to sell. It can work against you if you don't have the right reason for users to spend time on your site.
Customers looking for quick answers want the correct solution in the shortest amount of time.
They don't want a sticky site. Knowing when to be sticky and when not to be sticky is my specialty. Don't let your investment in the internet work against you by building a site that wastes your customer's time.
