Sharon Housley of FeedForAll hits the nail on the head in her article The Future of RSS is Not in Blogs.
RSS feeds give readers a tremendously powerful tool to find and read the stuff which interests them.
Blogs give writers soapboxes from which to spread their witticism.
Most people are readers and “should” care about RSS feeds. Few people are writers so few will have interest in writing blogs. (Can you see my biases peeking through?)
From Housley’s article:
The biggest opportunities for RSS are not in the blogosphere but as a corporate communication channel.
RSS, being a tool that saves Internet surfers time and allows webmasters to re-purpose and re-package existing and new content will, in my opinion, continue to thrive. A business effectively using RSS can bring new site visitors, increase search engine positioning, and generate product interest. The flexibility of RSS as a communication medium and the expansion capabilities of the enclosure tag will allow RSS to flourish as an online marketing tool. Each day businesses are adopting new uses for RSS, and users are becoming accustomed to skimming content that *they* choose in a single centralized location.
