I wish the default action would be Wall-to-Wall...alas...it's left up to the user to actually READ... and we all know how that's gonna end up.
One thing that bugs me multiple requests to Causes and Applications. Hello...If I turned you down on Vampire Bites once...it's gonna happen again...and again... give it up... and don't get pissy with me about it. It's not a reflection on you...I'm not into all the novelty apps on Facebook.
I orginally thought that voice chat would be the best enhancement to SL. Haveing read your post and thought more about, I think I will pass on it. Sure it will have some use. It will be cool to do streaming from within SL and have more voices available in podcasts but aside from that I reckon (sorry for the southern reference, but it was the best word) it will be akin to party lines. Too many voices to make a conversation followable.
The number of times that I've been involved in a Skype chat within SL, I've found that I resort to text to express myself clearer. I know several podcasters that would benefit from voice conversations vs text since they suck at typing, but I think they are the exception to the rule.
I for one will continue to visit Nowhereville if there is voice there or not. It's all about the people that go there...not so much what's going on.
