SE Trick – Modify RSS Feed URL using jQuery
This is a simple tutorial (to the original question) on how you can replace your existing StackExchange questions feed link with a third-party feed tracker service such as FeedBurner.
By default, your questions feed should look something like: http://{SITE_NAME}/feeds where you will also have answers feed: http://{SITE_NAME}/feeds/question/{QUESTION_ID}, user feed: http://{SITE_NAME}/feeds/user/{USER_ID} and tags feed: http://{SITE_NAME}/feeds/tag?tagnames={TAG_SLUG}&sort={SORT_VERB}.
Using simple jQuery, you can replace existing questions feed link to specified URL without effecting other feed links:
$(document).ready(function()
{
if($("#feed-link-text a").text() == "recent questions feed")
{
$("#feed-link-text a").attr("href", "{NEW_FEED_URL}");
}
});
Done!
