I have seen companies tried, and worked for a strategic consulting firm at one time who was heavily reliant on RSS feeds for sending information (we were basicly human parsers on very topic-specific items). And they used NewsGator. I get the impression NewGator is not doing that well, and the "I will pay good money" sector you suggest exists does not; very few people are willing to pay for good interface, despite a strong use case. I say the same about movies and television. There is a self-serving expectation of free, and few buck this trend unless they really need it and the pay-for services are not worth it, or do just enough. Maybe others can tell me their experiences.

I am definitely someone affected by this, and continue to look into better RSS management every year or so for this reason. It appears building my own solution is by far the best approach, and that is true for a whole bunch of software anyway. Oh well.
