Gadgetorama has been using Feedburner for its RSS feed for some time. Nothing really changed when Google purchased the service a while back but they have been making a number of changes since then.
One change that is taking place is a migration to a Google-branded service. Today, I took the plunge and migrated the Gadgetorama feed over, thereby changing the link to the RSS feed. While the old link will still work, I would recommend that you update it nonetheless. The new link is: http://feedproxy.google.com/gadgetoramanews/.
As always, let me know if you run into any issues!
