This poses challenges - as the service grows, Alexander Marktl will have to think carefully about how to prevent spammers from using the service. But on the other hand, it will support real journalism (rather than just linking to popular TechCrunch-articles and being shown in the long tail of a TC-post).

But there's something more important: ReadBurner provides the interface to Google Reader that they should have developed themselves. It has the potential of creating customized ReadBurner-pages, where only the stories count that your friends shared with you. Something that TechMeme can't ever do.

Easy Way:
- Got to http://technorati.com/technology/
- On the far right side of the page you will see Tags from what’s rising
- For example sake click on the blogging tag
- You will then transfer (or should) to http://technorati.com/tag/blogging
- In the upper right corner of the page - right across from the headline listing how many posts are tagged with blogging you will see the RSS button with Subscribe beside it
- Now before subscribing using the provided link in the area just under the Post Tag title you will see the drop down list which is where you can specify the authority you want for the feed.

A way to build a more complex type of Tag RSS feed is to switch to the Advance Search page and scroll down the the Tag Search Section. In the area provided just create the search string that includes the tags you want - i.e.: blogs OR Facebook OR Social Networks .

then click the search button and the resulting page from the search will also have that same RSS subscribe button.

This though IMO is the one area that Technorati needs to do some really serious work but if they do it right they could literally change the face of how we use our RSS readers.
