I see what you're saying but I am not suggesting that people would use all these services all the time. The point is that you would have a choice of "getting" your content in the application you are most comfortable with. Imagine if you are a daily user of TweetDeck and know how to filter your content (so you have relatively mastered the information overload already). Now, wouldn't it be better for you if you could pull in RSS feeds as well into TweetDeck?

I don't think it does. If Tumblr had their own reader, you wouldn't have to visit X sites - you could just visit Tumblr.

Maybe I am misunderstanding your ideas but I guess I don't see the benefit of visiting Tumblr's RSS reader to read Tumblr. Why not just read from Tumblr's website at that point?

I think the original commenter's point was that they frequently use Tumblr's current method of reading other Tumbls, and they would prefer that other web content appear there, too.

It's not visiting Tumblr's Reader to read Tumblr - it's visiting Tumblr's Reader to read everythign.

If Google+ can't fathom a use for RSS, why should Tumblr?
