I've read about Nings but they really must be seen to be understood. The Texas School Librarian Ning appears to be a mashup of youtube videos, a couple of wikis, assorted blogs, some forums, a few yahoo groups and LM_NET. It really is LM_NET with graphics and ads. I wonder if it's moderated as LM_NET is?
Of course I joined. Not that I need yet another Web distraction but I couldn't resist. I also found yet another blog to add to my google reader. Information overload, here I come!
