Mobile browsing of Leaderboards, via Mowser
So of course, a nice application did appear: a web app for mobile browsing of the Techmeme Leaderboard. The great thing about it is how clicks on sources naturally give way to post summaries, which give way to original posts, all of it rendered for mobiles.
It's a very smart combination of the capabilities of Mowser, a mobile transcoding service and the data contained in the Leaderboard's OPML feed. For more on this see this post by Russell Beattie, Mowser's founder, and his followup where he introduces a companion service for memeorandum's Leaderboard.
Mowser's Leaderboard services are a special case of "OPML grazing", for which general apps have appeared in recent years. Last fall, Ross Mayfield embedded a grazing widget powered by Grazr in this post which similarly uses the Techmeme Leaderboard's OPML as a starting point. You can customize your own Grazr Leaderboard widget starting at this page. They also offer iPhone-optimized grazing. Several RSS aggregators have similar capabilities built-in. Blogbridge's Pito Salas, for instance, explained how the OPML file could enable a Techmeme Leaderboard "Reading List" subscription.
If you know of any more applications for the Leaderboard OPML feeds, please let me know.
