If you publish on multiple places like HubPages, YouTube, Twitter, and other blogs and wish you had one RSS feed that aggregated all your RSS feeds into one single feed, here is a simple way to do it.

Step 1. Go to each site you publish on and copy the URL to your RSS feed. To find the URL to the feed, you can click on the little RSS icon in most browsers in the URL bar and then copy the URL. Here is an example of three places I place content.

http://feeds2.feedburner.com/TrainThoughts

Step 2. Go to Friendfeed.com and open an account. Once you have an account you can add/edit services. Add the RSS service for each one of your feeds.

Step 3. After all feeds have been added, click the "Me" link on the right hand side of the page. Then go to the URL bar and click the RSS Icon. Copy that RSS Feed and you will have your feed of feeds.

Why would you want a feed of feeds? Well, for one you can create a widget on widgetbox with your feed and then post your widget on your blog or other places. Second, if your feed is all personal stuff, you can give it to family members, and then they can easily see all your blog posts, pictures and videos and don't have to remember all the places you post stuff.
