Clearly the link is more important than the link description. There is a really surprisingly good document [here] that explains why in detail :P

You never should use "here" for links. It's bad semantics for hyperlinks, and there could be tens of thousands of links with the title "here." Compare:

> [The W3C recommends not using "here" or "click here" for links.](https://www.w3.org/QA/Tips/noClickHere)

According to the original vision of hypermedia, the text should be able to stand on its own and the hyperlinks are added on top of it. This keeps the link text semantic by itself without relying on the hyperlink.

In html the link comes first <a href="link">Link Text</a>. So I would bet that most people are more comfortable with the link coming first.

I'd argue that if you are writing text, you'll put the description first and then look up the link. Because the description is often part of the sentence, and the link is not.

In fact you may write the entire thing first then look for whatever can or should be hyperlinked.

Most people wouldn't be able to explain to you what a HTML tag is, much less write one.

And the entire point of Markdown is to get something that is closer to how we write plain text.

I'm more comfortable with the text coming first, followed by the link. The rails `link_to` helper is:

> link_to "Text", "http://example.com"

And Markdown:

> [Text](http://example.com)

It's pretty easy to remember the order after a while.
