What does LinkPeek mean?
LinkPeek is the combination of the work "link" and "peek".
Link is short for "hyperlink" a piece of text that may be clicked on to travel to another web page. Peek is the act of sneaking a look at something. Put them together you have LinkPeek.
Originally the usecase for LinkPeek was to be a Link previewing service. Allow users to peek at a link without traveling to it.
Since then LinkPeek's functionality has increased but the name stays the same.
