Less pretty and I can't click on it. [For me a custom link type is fine,
but every line of customization makes it harder to reproduce down the
road].
Anyway, I found out that mathjax upstream now support labeling to
equations using the latex format. Try:
In equation \eqref{eq:sample}, we find the value of an
interesting integral:
\begin{equation}
\int_0^\infty \frac{x^3}{e^x-1}\,dx = \frac{\pi^4}{15}
\label{eq:sample}
\end{equation}

I definitely think it is the more proper way to refer to an equation. But
it really depends on the document. E.g. mathtools also offer a set of
commands for referring to equations. I was considering an alist of
(DESTINATION-TYPE REF-CMD-WITH-DESCRIPTION REF-CMD-WITHOUT-DESCRIPTION)
But it might be an overkill, especially seeing that mathjax only supports
\ref and \eqref out of the box.
