This is a little tip where if you're using an external web feed management provider like Feedburner for your blog feed, your feed url looks more professional if it uses your own domain name instead of a third party domain name.
I use FeedBurner so in my case, instead of feeds.feedburner.com/onwebusability, it's at feeds.examinemysite.com/onwebusability . There's no cost in doing this. Hopefully your web host gives you access to your dns entries. If not, have them do it for you manually.
In addition, the benefit of using your own domain name is having more control. If for example Feedburner goes down for days or goes out of business, you will not lose your subscribers. You just make a quick dns change and redirect the subscribers to another feed location such as the blog's own feed.
I followed these instructions to make the necessary changes at my host and at Feedburner. Good luck.
