I noticed two changes these past few days to the onebox in Google Search. The first is that multiple submissions (3 seen) are now showing within the 7-pack and the other is that the rankings move around. Mine moved from #1 to #2 to #3 and today it's back at #1.

I have not seen any changes in 7-pack appearance. However, the rankings do seems to toggle up and down at different times of the day for a particular query that I track regularly.

Same here, depending on the time of the day mine goes up or down. But for the most part it holds elnumero uno spot.

Was surprised to get an email from Google to say that my listing in the LBC was offline because I hadn't authenticated with the PIN. What? I had done so more than once.
The note in the control panel said that they had sent a postcard back in 2007!
Anyway, re-authenticated by phone and got back, at the bottom of page 8. :(
