1) A lesson for marketers is to make our web sites, products, etc., compatible with largest possible number of users, including most common browsers and computer systems.

The vast majority of web surfers use Internet Explorer, with Netscape in distant second place. The most popular screen resolution is 800 x 600.

This also means avoiding or using extreme caution with newer technology that people with slower connections and older computer systems can't easily use. One exception may be if you cater to an especially high-tech target market.

2) Unless you have a good reason to deviate from default hyperlink colors, it's best not to. Typically, blue links have not been visited, and purple links have. Other non-link text colored blue or purple may confuse visitors by making them think they are links.

3) A common pet peeve among surfers is slow-loading web pages. When using images on your pages, use width and height attributes in HTML code to specify image sizes. Browsers can then allocate proper space for images and text can start loading (giving visitors something to view) while images load.
