Valid point. However, NewsGator, FeedBurner and FeedReader are all well aware of that fact. I've been part of a consumer-grade RSS startup myself. We were trying really hard to educate users (we made a big deal about it) we've been trying to avoid using RSS word, we had web-version (like yours), we had IE plugin and FireFox plugin (!), but ultimately came short of inventing a working business model. Too much competition, too few customers. My startup survived (switched to business customers) and I believe you're coming to the market too late.
