Well, you could also do:
$("h1").prepend("§");
The reasoning behind handling selectors (and HTML) in $(...) and then later
appending/prepending/etc. them into the document is that you can modify them
in the interim.
For example:
$("<h1>Something</h1>").click(function(){ .... }).prependTo("div.section");
Whereas there's really no associated use case for pure text nodes.
