SP2010 Sitemap provider listing

Scenario:
Provider model was one of the best enhancement we saw in ASP.Net 2.0 and SharePoint is kinda designed to used to best of dot net framework so that end user / developer waste less time to create something quickly.

CurrentNavigation is the default provider when you create a web application.
In my experience GlobalNavigation, CurrentNavigation and SPXmlContentMapProvider providers are most commonly used.

Here's list of all the providers available in SP2010 with description.
