I got the Beta, didn't realize it was out of Beta now. Interesting. Haven't used it much other than to ooh and aah over the shiny and peruse the settings a bit. Only thing I think is really missing is the ability to add people to your friend list, unless you already can and I missed it.
EDIT: On an unrelated note, I have determined that my connection woes are the fault of either our router or our ISP. I'm guessing it's the ISP since we had a major snowstorm a couple of weeks ago. That said, the problems started shortly before the snow came in and it's been two weeks since, so idklolbffjill.
