I have RSS feeds like mad on my sites, but it seems that tons of folks are using some nonsense called “Feedburner” and I can’t seem to grasp what the benefits of it are.
Can someone summarize a form of “Feedburder for Dummies” for me? Thanks.

Its a RSS directory where bloggers submit the feeds of their blogs and whenever there is a new update on the site, its being updated on this directory as well. It serves an automatic social bookmarking of your blogs via RSS. It is beneficial because you dont have to enter the URL of your new posts as its automatically fetch by the site.

Feedburner is Google alternative to its own blogger feeds.
Not sure which one works best.
Both work about the same.
My issue would be how to get more subscribers and have them KEEP coming back and not unsubscribe so often. The blog in question has daily updates on par with current news events and such. But I seem to can’t get and stay over 300+ subscribers yet the site gets about 7000 uniques a day.
One of the benefits of Feedburner is that you can take feeds from blogs that you write and use Feedburner to post them directly to your Twitter account without needing to install an additional script on either the blog or twitter to do it. Useful where you have a blog where you don’t have access to install a twitter feed plugin on it.
