Here’s a quick review of an RSS submission site at http://www.rsshugger.com. Instead of paying to get my site listed in on their site you can opt into posting a simple blog with a link back to their site. It’s a well designed website with an okay Alexa rating. The important thing is the link to your blog and the continually updated content there on their site. I think it will grow into something big in the near future. Check it out!
There are also many other sites out there you can submit your RSS feeds to that will increase your readership and rankings in the listings. I know this blog is mainly entrepreneurship and Personal Development, but look for a post in the near future with a list of sites to submit your RSS feed to.
