It seems to me that there are a ton of
<meta> tags for all sorts of different purposes out there...
Though they all follow a similar format of
<meta name="" content="" />
they seem to serve a vast variety of different purposes from controlling the crawling of search engine bots, providing search engine bots with descriptions of pages, to making sure a page display correctly on a mobile device.
These tags fall into so many different categories I was wondering if anyone had a wiki or master list of possible meta tags and their content.
