CNET offers podcasting help already. They don't need to offer a blogging service. If they did, it would not be as clean as some of the other ones such as Blogger, Typepad, and Wordpress. What type of rss feed service do you want? Just get a feed reader and find some feeds on websites.
The problem with personalized services is that people are thinking that if you use the term Web 2.0, the service will attract users and then get bought by Yahoo or Google. I really don't see many "Web 2.0" sites around in 2-3 years, at least in their current form where they offer the service for free.
I know this isn't a video but I can't make one because I don't have a video recorder.
But I still want to make a suggestion.
Why doesn't Cnet expand from just doing news blogs and also become a bloging service?
Or mabye they could be a rss feed service or be a podcasting help service that helps people make podcasts?
Huh? Eh? How bout it?
