While it may seem rude (and partially is due to this), some of it is because of repetition. Allow me to explain.
I've been lurking those forums for... who knows how long now. I can't tell you HOW many people post the same topic, asking if there are stars, if they're testing them, when they will be deployed, if anyone has them, complaining about att/weather not having them, asking the greek gods to implement them, and various other forms. I'd say that as far as I was watching, the amount of these posts have easily hit the few hundred mark. Just from what I could say.
Some people are rude, yes. Some people absolutely hate it. And others are just sick of seeing 'why don't i have local weather' posts and will say 'search the forums'.
A lot of us u-verse users want it. Have wanted it. E-mails to weather channel simply say 'at&t needs to implement it', and emails to at&t go un-answered. So the truthful answer is... no one knows. at&t has this amazing tendency on leaving people absolutely in the dark on upgrades and updates. Markets in Texas will have something months if not a year before everyone has it. Channel additions randomly pop up.
If (BIG if) at&t ever decides to put a star in, you'll probably see 3 billion posts about how pigs are flying on there. But it'd only be in Texas for a while. :/ So my suggestion is to cautiously watch the forums. When something pops up, you know it'll be around the corner. Because people reporting it is the closest thing you'll get to a response since god knows at&t won't answer questions.
