We wrote about Nuvvo, a brave startup taking on an open source competitor, last January. However, Nuvvo is now up for sale. And it may soon be entering the DeadPool, depsite what the founders wrote on the Nuvvo blog:
This does not mean Nuvvo is shutting down. Our many thousands of users around the world are dear to us and we will keep the service going for the forseable future.
For a summary of recent small sales, many on ebay, see this post.
