Destroying Tumblr with RSS

Let's say, purely as a hypothetical, that I wanted to destroy Tumblr as a medium.  What would I do?

My idea is this: People on Tumblr are stuck there, because it's the only way to keep track of their news feed.  If you have friends on Tumblr and want to keep track of them, it's the only way.  Unfortunately, the news feed does not let you track anything that isn't on Tumblr.  So at that point, you simply stop reading things that aren't on Tumblr.

However, there is another way to track people on Tumblr!  There's something called RSS, which is used by old-timers like me.  All you need is an RSS reader, such as Feedly, and then you add subscriptions to anything you like. 

For instance! If I wanted to keep track of the Hiveswap tumblr:

http://hiveswapgame.tumblr.com/

Then I simply go to the rss feed:

http://hiveswapgame.tumblr.com/rss

And then there's the option to put it into Feedly!  This isn't tech-geek level stuff, it's really simple syndication (RSS)!

RSS offers many advantages compared to Tumblr.  You can subscribe to blogs that aren't on Tumblr.  You can subscribe to webcomics.  The world is ripe for the taking!

The Tumblr news feed also offers a few advantages:

1. What the hell is RSS?
2. The Tumblr news feed is easily accessible.
3. Tumblr doesn't keep track of how much you've read, so there's no anxiety over unread counts
4. Tumblr lets you keep track of tags, which as far as I know, have no associated RSS feed.
5. I've already subscribed to a lot of Tumblrs and it's too much work to subscribe to each and every RSS feed.
6. What the hell is RSS?

So I'm thinking, purely as a hypothetical, that I need to find a suitable RSS reader, one which is so simple even a Tumblrite could use it.  Then I need to make a good tutorial/sales pitch to convince people to use it.

Does anyone have any suggestions?  Which RSS reader would work best?  How can I write the sales pitch?  What sort of pitfalls might a person encounter when switching from Tumblr to RSS, and how might I solve them?
