I moved to Moniker a couple years ago since there was so much praise for it on Slashdot. I didn't check out the new interface yet. I don't have that many domains, but if they're so interested in obliterating their core functionality for no real reason, I think I'll play it safe and look into migrating registrars.
I'm in the same boat. A handful of domains, moved there because of Slashdot. If I hadn't seen this story on HN, I could have lost all of my domains upon their expiration: my contact email reverted to an email I haven't used in years and it appears my credit card reverted to an old (now invalid) number.
