Feedpass offers to provide a single page allowing your website visitors to easily subscribe to your blog RSS feed using all services possible.
Each visitor has their own favourite way of reading blogs. Some use rss aggregators like Bloglines, MyYahoo, Rojo etc. Some like rss to email delivery of your posts using services like rmail, rssfwd or feedblitz. It provides quick links to all these services to let readers subscribe to your blog easily. Then it lists the headlines of the most recent posts from your feed and lets users bookmarks your posts on social bookmarking tools like del.icio.us, furl, spurl, etc..
I created my Feedpass page here. You can have a look before you decide to create your own feedpass page.
Feedpass lets you earn extra money from your feedpass pages if you add your Google AdSense id code. The targeted contextual ads which load on that page will display ads with your Google adsense id and will earn you money when people click on them. [You do not see any Adsense ads on my page because I have not added my Adsense id to that page (too cautious!)]
