Has anyone else noticed the Ajaxian “Register for Interest” pattern sported by the new-skool stealth startups? The new Firefox+++ project, Flock (via Ajaxian) is doing it right now.

Essentially, “This is happening in a few weeks, leave your mail, we won’t spam you, and we’ll tell you about it.”

I submit my email.

Then the page morphs and thanks you for your interest. (Not altogether different from Lazy Registration.)

And if Flock is different to the last one I tried, they’ll actually send something back.

Update: They’ve auto-mailed me an invite to join a mailing list. I guess they can’t do RSS due to auth issues, but I’m going to skip on the mailing list offer.
