I see more and more people using Aweber's blog broadcast service as well as or even instead of an RSS button on their blogs.

This service will send an email to your list whenever you make a new post on your blog. And they just recently added the ability to schedule it, so you can send one a day with all posts for the day, a weekly digest or whatever else you might prefer.

It gets that information from your RSS feed, just like a feed reader does.

So what's the big advantage?

The main thing is the portability. If you ever decide to move your website to a new domain, and it does happen even if you would never expect to have to do it, all those people who subscribed to your RSS feed are going to be pulling from the old domain name.

If you use Aweber's service, all you need to do is log in to your Aweber account and change the RSS feed address on the blog broadcast setup. All the people who subscribed to the email updates are still there and will start getting the new domain in the updates, possibly without even noticing the change.

Now the other option is to use a service like Feedburner. They process your RSS feed and your subscribers get a Feedburner address to subscribe to. Again, change the settings on the Feedburner setup and all the people subscribed to it continue to get your updates.

The only problem I have with Feedburner is they do some funky stuff every now and then. I'm not sure what they do to cause it, but every so often they refresh the feed URL somehow and it causes a lot of news reader software to reload all the past posts because it thinks they're new ones.

It's not a huge problem, but it's a pain when I'm going through my feeds and suddenly have to pick through a bunch I've already read.

I'll be adding an Aweber blog broadcast subscription form here in the next day or two, once I test it a bit on another site so I'm sure I know how to set it up properly.
