Marjolein Hoekstra of CleverClogs passes along a very interesting link that shows a weakness in the RSS infrastructure that would be solved by the new Bloglines' Feed Access Control. Now, I'm unsure how this feed got into FeedShow, I don't seem to have an account with them. I assume they are pulling information from otherplace to seed there database, but I'm just guessing. Maybe I've subscribed to this private feed in another aggregator and since the authentication data is contained within the subscription URL, the credentials are made public somewhere along the route from del.icio.us to FeedShow. Unfortunately, since Feed Access Control is an extension of RSS, few providers are gonna implement this and the solution is not perfect, but it's better than nothing. This is far from the first time where private feeds become public via an online RSS aggregator, you may remember the Gmail/Bloglines problems.

Thierry,
I'm just using the FeedShow example as a sample. I'm not actually interested in protecting that feed.
Thanks anyways,
Randy
