Yahoo Pipes tool for generating RSS feeds for certain tags

Hey there. I've created a Yahoo Pipe that generates an RSS feed for tumblr posts tagged with a certain tag: http://pipes.yahoo.com/crimesceneimpr.... After running the tag, right-click 'rss' and fetch the feed url, then link to it in your tumblr description. This is an inelegant way of solving a big problem with Tumblr: it's great for creative types, but makes it virtually impossible for creatives to promote their work, simply because they're throwing so much scrapbook-style stuff in with the original content. A budding writer, for example, might want some way to showcase her longer essays. No potential client or employer will want to wade through all the one-liners, Youtube videos, etc. RSS is, of course, related-- the sheer volume of content can be quite off-putting.
Tumblr's archive page is fairly preposterous; I suggest actively tagging original content, and including links to some important tags at the top of the page, along with a link to the rss feed of that tag.
