Answer.com's AnswerTips is an easy way for your visitors to find out the definition of any word on your website without leaving it. Many websites use industry language. For a majority of visitors this may be understood. However for some it may not be. This is an easy and clean solution for any site.
The positive and negative is when applied to a website the AnswerTips links are not intrusive. Without thier banner ad describing that you can double-click a word a visitor may not be aware of this feature, at the other hand would you really want every word on your website underlined or highlighted? As time goes on and this service becomes more popular, the banner ad may not be required.
This blog has now been AnswerTips enabled, so go ahead double-click any word. We dare ya.
