The similarity of a business on the web makes a good metaphor. Changes in web technology will inevitably come and disrupt our normal routine online. Where we have grown used to one way of doing business, it could change dramatically overnight. I have found that portions of the content on my web site are becoming dated and in some cases, completely inaccurate. Some of the sites I have linked to and relied on for content have evolved into something else or fallen down themselves.
Dynamic content replaces static pages.
New, more valuable services grow and replace the old, just as is the case on these huge oak trees. Banner ads become less effective, e-mail marketing grows and adds a new, vital branch to a massive tree. Some will mourn the loss of the old branch, try to graft it back to the tree, curse the damage it did to the flower garden below and wail at the cost of cleaning it up. Others will take it as routine for the life of the tree, then rejoice in the free firewood and look forward to re-doing the flower bed with new varieties in the spring. Go in search of new, more valuable and dynamic content for your site.
