I love rivers. I think it's the best way to get content. If you don't check the river for awhile and miss some things - so what? Just let it float down the river. I even made some rivers out of Google alert RSS feeds; just as a way to find completely random content. Can't do that anymore :(
But this nurse river I made - there's a problem. No one is writing any interesting content anymore. Back in 2005-2007 there was a vibrant little community of nurse bloggers. Almost all of them have given it up. The ones that are around now are just posting little blurbs and pictures, or else really, really dry accounts of current nursing research. The storytelling is long gone.
A blogging community should be at least as interesting as the fodder you hear in the breakroom. If we can't find a way to bring that back then maybe it's time to really admit that nurse blogging is over.
