According to a research published by Diretgov, half of UK internet users regularly visit just 6 websites on average. 95% also say that they go online with a specific destination in mind (what happened to "web surfing"?).
Steve Rubel thinks that this could explain why RSS hasn't taken off yet. I agree, most people don't need to keep a watch on dozens of websites or blogs, so see little use for an aggregator or feed system. The fact that RSS feeds are not user-friendly enough for the average web users doesn't help either. This could confine RSS to innovators or professional usage for a while.
