Unfortunately most off-the-shelf website building tools aimed at non-technical users don't offer any form of RSS feed option. Often it is impossible to integrate it, and if it is possible, it is either a complicated integration process, or only available as a piad extra.
Every single page of your website could be published as an RSS feed, get listed fast in search engines and automatically pinged to many RSS agregators and directories. Your subscribed customers could be updated immediately with all changes to your website, not just posts in your blog.
Site Build It
The most complete non-technical solution is to use Site Build It (SBI). It is designed as the ideal tool to help a non-technical user create a valuable high content website that pulls in traffic. Being RSS enabled, not only does it help bring in more traffic, but it also greatly increases the stickiness, and the number of repeat visits. It is the perfect RSS website builder.
It is easy to turn your hobby or passion into a profitable business, and it is one of the most powerful tools used by home based business. What many people don't realise is that SBI is also used by web design professionals.
Ok but what about the professional niche website builder, who already has a number of SBI sites, and is experimenting with a large amount of new niches, and doesn't want to invest $300/year in a site he is not 100% sure about.
Here are 2 very good options

Content Management Systems
I haven't actually played with this option myself, but I have noticed that some of the open source content management systems (CMS) such as Mambo also have the facility to produce RSS feeds of their content.
I have seen a number of websites created using this system by people experienced in internet marketing. One of the reasons I haven't delved into this too greatly is time. Many of the sites using this seem to have "broken" RSS feeds, you try to add them to your RSS reader and it doesn't seem to work.
RSS is complicated enough for most users, just as a concept - if your implementation isn't idiot proof, you are not helping your customer. Using a complicated CMS system is only an option if you have the knowledge to create a seemless end user experience.
