I've been getting them occasionally, too. It's part of the 2010 redesign. Currently, some staff members are using the new layout in order to test
for glitches before the public launch. When they reply to a post while on the 2010 theme, members will receive a u2u announcing they received a
response to the post.
I do believe the feature will be able to turned off in your preferences once the launch is public, though.
